Cannot perform operation after producer has been closed

抱歉,这不是一个问题。这是一个错误信息,通常是由于尝试在 Kafka producer 关闭后继续发送消息引起的。在使用 Kafka producer 时,需要确保在发送完所有消息后,使用 `close()` 方法关闭它。如果需要在关闭 producer 后继续发送消息,需要重新创建一个新的 producer。

启动报错Cannot perform operation after producer has been closed
这个错误通常是由于在 Kafka Producer 已经关闭之后,仍然尝试对其进行操作所导致的。这可能是因为在 Producer 关闭之前还有消息未发送完毕,或者在关闭之后意外地尝试重新使用 Producer。
解决方法是在关闭 Producer 之前确保所有消息都已经被发送和确认,或者在每次使用 Producer 之前都要先检查它的状态,确保它处于可用状态。另外,也可以考虑使用自动管理 Kafka 连接的第三方库,以避免手动管理连接状态时出现的错误。
I/O operation on closed file.
As an AI language model, I do not have access to the context of the error message you provided. However, in general, this error message indicates that a program or script attempted to perform an input/output (I/O) operation on a file that has already been closed. This can happen when a file is closed prematurely or when a program tries to access a file that has already been closed. To resolve this issue, you may need to check your code to ensure that files are not closed before all necessary I/O operations have been completed. Additionally, you may need to handle file exceptions and errors to avoid unexpected program termination.
