Build a Time Series Application with Apache Spark and Apache HBaseCarol McDonald
This document discusses using Apache Spark and Apache HBase to build a time series application. It provides an overview of time series data and requirements for ingesting, storing, and analyzing high volumes of time series data. The document then describes using Spark Streaming to process real-time data streams from sensors and storing the data in HBase. It outlines the steps in the lab exercise, which involves reading sensor data from files, converting it to objects, creating a Spark Streaming DStream, processing the DStream, and saving the data to HBase.
Talk at Hug FR on December 4, 2012 about the new Apache Drill project. Notably, this talk includes an introduction to the converging specification for the logical plan in Drill.
From the Hadoop Summit 2015 Session with Ted Dunning:
Just when we thought the last mile problem was solved, the Internet of Things is turning the last mile problem of the consumer internet into the first mile problem of the industrial internet. This inversion impacts every aspect of the design of networked applications. I will show how to use existing Hadoop ecosystem tools, such as Spark, Drill and others, to deal successfully with this inversion. I will present real examples of how data from things leads to real business benefits and describe real techniques for how these examples work.
Impala is a massively parallel processing SQL query engine for Hadoop. It allows users to issue SQL queries directly to their data in Apache Hadoop. Impala uses a distributed architecture where queries are executed in parallel across nodes by Impala daemons. It uses a new execution engine written in C++ with runtime code generation for high performance. Impala also supports commonly used Hadoop file formats and can query data stored in HDFS and HBase.
Operating multi-tenant clusters requires careful planning of capacity for on-time launch of big data projects and applications within expected budget and with appropriate SLA guarantees. Making such guarantees with a set of standard hardware configurations is key to operate big data platforms as a hosted service for your organization.
This talk highlights the tools, techniques and methodology applied on a per-project or user basis across three primary multi-tenant deployments in the Apache Hadoop ecosystem, namely MapReduce/YARN and HDFS, HBase, and Storm due to the significance of capital investments with increasing scale in data nodes, region servers, and supervisor nodes respectively. We will demo the estimation tools developed for these deployments that can be used for capital planning and forecasting, and cluster resource and SLA management, including making latency and throughput guarantees to individual users and projects.
As we discuss the tools, we will share considerations that got incorporated to come up with the most appropriate calculation across these three primary deployments. We will discuss the data sources for calculations, resource drivers for different use cases, and how to plan for optimum capacity allocation per project with respect to given standard hardware configurations.

We use MapReduce programming paradigm because it lends itself well to most data-intensive analytics jobs run on cloud these days, given its ability to scale-out and leverage several machines to parallel process data. Research has demonstrates that existing approaches to provisioning other applications in the cloud are not immediately relevant to MapReduce -based applications. Provisioning a MapReduce job entails requesting optimum number of resource sets (RS) and configuring MapReduce parameters such that each resource set is maximally utilized.
Each application has a different bottleneck resource (CPU :Disk :Network), and different bottleneck resource utilization, and thus needs to pick a different combination of these parameters based on the job profile such that the bottleneck resource is maximally utilized.
The problem at hand is thus defining a resource provisioning framework for MapReduce jobs running in a cloud keeping in mind performance goals such as Optimal resource utilization with Minimum incurred cost, Lower execution time, Energy Awareness, Automatic handling of node failure and Highly scalable solution.
Enterprise Scale Topological Data Analysis Using SparkAlpine Data
This document discusses scaling topological data analysis (TDA) using the Mapper algorithm to analyze large datasets. It describes how the authors built the first open-source scalable implementation of Mapper called Betti Mapper using Spark. Betti Mapper uses locality-sensitive hashing to bin data points and compute topological summaries on prototype points to achieve an 8-11x performance improvement over a naive Spark implementation. The key aspects of Betti Mapper that enable scaling to enterprise datasets are locality-sensitive hashing for sampling and using prototype points to reduce the distance matrix computation.
The document discusses using Hadoop MapReduce for large scale mathematical computations. It introduces integer multiplication algorithms like FFT, MapReduce-FFT, MapReduce-Sum and MapReduce-SSA. These algorithms can be used to solve computationally intensive problems like integer factoring, PDE solving, computing the Riemann zeta function, and calculating pi to high precision. The document focuses on integer multiplication as it is a prerequisite for many applications and explores FFT-based algorithms and the Schonhage-Strassen algorithm in particular.
The document discusses the potential for OpenStack to be the future of cloud computing. It describes how OpenStack provides an operating system for hybrid clouds that can augment and replace proprietary infrastructure software. The timing is optimal for OpenStack to accelerate the shift to cloud computing as enterprises look to adopt cloud solutions and ensure new applications can access corporate data and systems. OpenStack is an open source project that could emerge as the standard approach and prevent vendor lock-in.
Apache Hadoop project, and the Hadoop ecosystem has been designed be extremely flexible, and extensible. HDFS, Yarn, and MapReduce combined have more that 1000 configuration parameters that allow users to tune performance of Hadoop applications, and more importantly, extend Hadoop with application-specific functionality, without having to modify any of the core Hadoop code.
In this talk, I will start with simple extensions, such as writing a new InputFormat to efficiently process video files. I will provide with some extensions that boost application performance, such as optimized compression codecs, and pluggable shuffle implementations. With refactoring of MapReduce framework, and emergence of YARN, as a generic resource manager for Hadoop, one can extend Hadoop further by implementing new computation paradigms.
I will discuss one such computation framework, that allows Message Passing applications to run in the Hadoop cluster alongside MapReduce. I will conclude by outlining some of our ongoing work, that extends HDFS, by removing namespace limitations of the current Namenode implementation.
This document provides an overview of Apache Spark, including:
- A refresher on MapReduce and its processing model
- An introduction to Spark, describing how it differs from MapReduce in addressing some of MapReduce's limitations
- Examples of how Spark can be used, including for iterative algorithms and interactive queries
- Resources for free online training in Hadoop, MapReduce, Hive and using HBase with MapReduce and Hive
This document provides an overview of Hadoop storage perspectives from different stakeholders. The Hadoop application team prefers direct attached storage for performance reasons, as Hadoop was designed for affordable internet-scale analytics where data locality is important. However, IT operations has valid concerns about reliability, manageability, utilization, and integration with other systems when data is stored on direct attached storage instead of shared storage. There are tradeoffs to both approaches that depend on factors like the infrastructure, workload characteristics, and priorities of the organization.
The document discusses best practices for scaling Hadoop applications. It covers causes of sublinear scalability like sequential bottlenecks, load imbalance, over-partitioning, and synchronization issues. It also provides equations for analyzing scalability and discusses techniques like reducing algorithmic overheads, increasing task granularity, and using compression. The document recommends using higher-level languages, tuning configuration parameters, and minimizing remote procedure calls to improve scalability.
Yahoo migrated most of its Pig workload from MapReduce to Tez to achieve significant performance improvements and resource utilization gains. Some key challenges in the migration included addressing misconfigurations, bad programming practices, and behavioral changes between the frameworks. Yahoo was able to run very large and complex Pig on Tez jobs involving hundreds of vertices and terabytes of data smoothly at scale. Further optimizations are still needed around speculative execution and container reuse to improve utilization even more. The migration to Tez resulted in up to 30% reduction in runtime, memory, and CPU usage for Yahoo's Pig workload.
The document discusses linking the statistical programming language R with the Hadoop platform for big data analysis. It introduces Hadoop and its components like HDFS and MapReduce. It describes three ways to link R and Hadoop: RHIPE which performs distributed and parallel analysis, RHadoop which provides HDFS and MapReduce interfaces, and Hadoop streaming which allows R scripts to be used as Mappers and Reducers. The goal is to use these methods to analyze large datasets with R functions on Hadoop clusters.
The document discusses how different technologies like Hadoop, Storm, Solr, and D3 can be integrated together using common storage platforms. It provides examples of how real-time and batch processing can be combined for applications like search and recommendations. The document advocates that hybrid systems integrating these technologies can provide benefits over traditional tiered architectures and be implemented today.
Anomaly Detection in Telecom with Spark - Tugdual Grall - Codemotion Amsterda...Codemotion
Telecom operators need to find operational anomalies in their networks very quickly. This need, however, is shared with many other industries as well so there are lessons for all of us here. Spark plus a streaming architecture can solve these problems very nicely. I will present both a practical architecture as well as design patterns and some detailed algorithms for detecting anomalies in event streams. These algorithms are simple but quite general and can be applied across a wide variety of situations.
This document discusses cloud and big data technologies. It provides an overview of Hadoop and its ecosystem, which includes components like HDFS, MapReduce, HBase, Zookeeper, Pig and Hive. It also describes how data is stored in HDFS and HBase, and how MapReduce can be used for parallel processing across large datasets. Finally, it gives examples of using MapReduce to implement algorithms for word counting, building inverted indexes and performing joins.
"Big Data" is a much-hyped term nowadays in Business Computing. However, the core concept of collaborative environments conducting experiments over large shared data repositories has existed for decades. In this talk, I will outline how recent advances in Cloud Computing, Big Data processing frameworks, and agile application development platforms enable Data Intensive Cloud Applications. I will provide a brief history of efforts in building scalable & adaptive run-time environments, and the role these runtime systems will play in new Cloud Applications. I will present a vision for cloud platforms for science, where data-intensive frameworks such as Apache Hadoop will play a key role.
Apache Drill is an open source engine for interactive analysis of large-scale datasets. It was inspired by Google's Dremel, which allows interactive querying of trillions of records at fast speeds. Drill uses a SQL-like language called DrQL to query nested data in a column-based manner. It has a flexible architecture that allows pluggable query languages, execution engines, data formats and sources. Drill aims to be fast, flexible, dependable and easy to use for interactive analysis of big data.
This document surveys and compares three large-scale graph processing platforms: Apache Giraph, Hadoop-MapReduce, and Neo4j. It analyzes their programming models and performance based on previous studies. Hadoop was found to have the worst performance for graph algorithms due to its lack of optimizations for graphs. Giraph was generally the fastest platform due to its in-memory computations and message passing model. Neo4j performed well for small graphs due to its caching but did not scale as well as distributed platforms for large graphs. The document concludes that distributed graph-specific platforms like Giraph outperform generic platforms for most graph problems.
This talk gives an introduction into Hadoop 2 and YARN. Then the changes for MapReduce 2 are explained. Finally Tez and Spark are explained and compared in detail.

There are a number of assumptions that come with using standard Hadoop that are based on Hadoop's initial architecture. Many of these assumptions can be relaxed with more advanced architectures such as those provided by MapR. These changes in assumptions have ripple effects throughout the system architecture. This is significant because many systems like Mahout provide multiple implementations of various algorithms with very different performance and scaling implications.
I will describe several case studies and use these examples to show how these changes can simplify systems or, in some cases, make certain classes of programs run an order of magnitude faster.

You’re not the only one still loading your data into data warehouses and building marts or cubes out of it. But today’s data requires a much more accessible environment that delivers real-time results. Prepare for this transformation because your data platform and storage choices are about to undergo a re-platforming that happens once in 30 years.
With the MapR Converged Data Platform (CDP) and Cisco Unified Compute System (UCS), you can optimize today’s infrastructure and grow to take advantage of what’s next. Uncover the range of possibilities from re-platforming by intimately understanding your options for density, performance, functionality and more.
The document discusses MapR's distribution for Apache Hadoop. It provides an enterprise-grade and open source distribution that leverages open source components and makes targeted enhancements to make Hadoop more open and enterprise-ready. Key features include integration with other big data technologies like Accumulo, high availability, easy management at scale, and a storage architecture based on volumes to logically organize and manage data placement and policies across a Hadoop cluster.
The document discusses MapR cluster management using the MapR CLI. It provides examples of starting and stopping a MapR cluster, managing nodes, volumes, mirrors and schedules. Specific examples include creating volumes, linking mirrors to volumes, syncing mirrors, moving volumes and nodes to different topologies, and creating schedules to automate tasks.
MapR is an amazing new distributed filesystem modeled after Hadoop. It maintains API compatibility with Hadoop, but far exceeds it in performance, manageability, and more.
/* Ted's MapR meeting slides incorporated here */
The open source project Apache Drill gives you SQL-on-Hadoop, but with some big differences. The biggest difference is that Drill extends ANSI SQL from a strongly typed language to also a late binding language without losing performance. This allows Drill to process complex structured data like JSON in addition to relational data. By dynamically generating a schema at read time that matches the data types and structures observed in the data, Drill gives you both self-service agility and speed.
Drill also introduces a view-based security model that uses file system permissions to control access to data at an extremely fine-grained level that makes secure access easy to control. These extensions have huge practical impact when it comes to writing real applications.
In these slides, Tugdual Grall, Technical Evangelist at MapR, gives several practical examples of how Drill makes it easy to analyze data, using SQL in your Java application with a simple JDBC driver.
MapR M7: Providing an enterprise quality Apache HBase APImcsrivas
The document provides an overview of MapR M7, an integrated system for structured and unstructured data. M7 combines aspects of LSM trees and B-trees to provide faster reads and writes compared to Apache HBase. It achieves instant recovery from failures through its use of micro write-ahead logs and parallel region recovery. Benchmark results show MapR M7 providing 5-11x faster performance than HBase for common operations like reads, updates, and scans.
This document discusses securing Hadoop with MapR. It begins by explaining why Hadoop security is now important given the sensitive data it handles. It then outlines weaknesses in typical Hadoop deployments. The rest of the document details how MapR secures Hadoop, including wire-level authentication and encryption, authorization integration, and security for ecosystem components like Hive and Oozie without requiring Kerberos.
Design Patterns for working with Fast Data in KafkaIan Downard
Apache Kafka is an open-source message broker project that provides a platform for storing and processing real-time data feeds. In this presentation Ian Downard describes the concepts that are important to understand in order to effectively use the Kafka API. He describes how to prepare a development environment from scratch, how to write a basic publish/subscribe application, and how to run it on a variety of cluster types, including simple single-node clusters, multi-node clusters using Heroku’s “Kafka as a Service”, and enterprise-grade multi-node clusters using MapR’s Converged Data Platform.
Video: https://vimeo.com/188045894
Ian also discusses strategies for working with "fast data" and how to maximize the throughput of your Kafka pipeline. He describes which Kafka configurations and data types have the largest impact on performance and provide some useful JUnit tests, combined with statistical analysis in R, that can help quantify how various configurations effect throughput.

Real World Use Cases: Hadoop and NoSQL in ProductionCodemotion
"Real World Use Cases: Hadoop and NoSQL in Production" by Tugdual Grall.
What’s important about a technology is what you can use it to do. I’ve looked at what a number of groups are doing with Apache Hadoop and NoSQL in production, and I will relay what worked well for them and what did not. Drawing from real world use cases, I show how people who understand these new approaches can employ them well in conjunction with traditional approaches and existing applications. Thread Detection, Datawarehouse optimization, Marketing Efficiency, Biometric Database are some examples exposed during this presentation.
MapR is an ideal scalable platform for data science and specifically for operationalizing machine learning in the enterprise. This presentations gives specific reasons why.
Ted Dunning presents on streaming architectures and MapR Technologies' streaming capabilities. He discusses MapR Streams, which implements the Kafka API for high performance and scale. MapR provides a converged data platform with files, tables, and streams managed under common security and permissions. Dunning reviews several use cases and lessons learned around real-time data processing, microservices, and global data management requirements.
Streaming in the Extreme
Jim Scott, Director, Enterprise Strategy & Architecture, MapR
Have you ever heard of Kafka? Are you ready to start streaming all of the events in your business? What happens to your streaming solution when you outgrow your single data center? What happens when you are at a company that is already running multiple data centers and you need to implement streaming across data centers? I will discuss technologies like Kafka that can be used to accomplish, real-time, lossless messaging that works in both single and multiple globally dispersed data centers. I will also describe how to handle the data coming in through these streams in both batch processes as well as real-time processes.What about when you need to scale to a trillion events per day? I will discuss technologies like Kafka that can be used to accomplish, real-time, lossless messaging that works in both single and multiple globally dispersed data centers. I will also describe how to handle the data coming in through these streams in both batch processes as well as real-time processes.

Big Data Everywhere Chicago: Getting Real with the MapR Platform (MapR)BigDataEverywhere
Jim Scott, Director of Enterprise Strategy, MapR; Cofounder, CHUG
In this talk, we will take a look back at the short history of Hadoop, along with the trials and tribulation that have come along with this ground-breaking technology. We will explore the reasons why enterprises need to look deeper into their wants and needs and further into the future to prepare for where they are going.
Spark is potentially replacing MapReduce as the primary execution framework for Hadoop, though Hadoop will likely continue embracing new frameworks. Spark code is easier to write and its performance is faster for iterative algorithms. However, not all applications are faster in Spark and it may have limitations. Hadoop also supports many other frameworks and is about more than just MapReduce, including storage, resource management, and a growing ecosystem of tools.
This document summarizes a talk given by Mathieu Dumoulin of MapR Technologies about architecting hybrid cloud applications using streaming messaging systems. The talk discusses using streaming architectures to connect systems in hybrid clouds, with public and private clouds connected by streaming. It also discusses using streaming for IoT and microservices and highlights Kafka and Spark Streaming/Flink as streaming technologies. Examples of log analysis architectures spanning hybrid clouds are presented.

How Spark is Enabling the New Wave of Converged Cloud Applications MapR Technologies
Apache Spark has become the de-facto compute engine of choice for data engineers, developers, and data scientists because of its ability to run multiple analytic workloads with a single, general-purpose compute engine.
But is Spark alone sufficient for developing cloud-based big data applications? What are the other required components for supporting big data cloud processing? How can you accelerate the development of applications which extend across Spark and other frameworks such as Kafka, Hadoop, NoSQL databases, and more?
MapR is a distribution of Apache Hadoop that includes over a dozen projects like HBase, Hive, Pig, and Spark. It provides capabilities for big data and constantly upgrades projects within 90 days of release. MapR also contributes to open source. Key benefits include high availability without special configurations, superior performance reducing costs, and data protection through snapshots. It also supports real-time applications, security, multi-tenancy, and assistance from MapR data scientists and engineers.

It then discusses predictive maintenance and how sensor data from industrial equipment can be used for failure prediction. The document outlines how a recurrent neural network model could be developed using streaming sensor data from manufacturing devices to identify abnormal behavior and predict needed maintenance. It describes the workflow of importing and preparing the data, developing and testing the model, and deploying it to generate alerts from new streaming data.
Ted Dunning is the Chief Applications Architect at MapR Technologies and a committer for Apache Drill, Zookeeper, and other projects. The document discusses goals around real-time or near-time processing and microservices. It describes how to design microservices for isolation using self-describing data, private databases, and shared storage only where necessary. Various scenarios involving fraud detection, IoT data aggregation, and global data recovery are presented. Lessons focus on decoupling services, propagating events rather than table updates, and how data architecture should reflect business structure.
Streaming Goes Mainstream: New Architecture & Emerging Technologies for Strea...MapR Technologies

Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora
Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik
This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik
Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.
