John Roesler created KAFKA-9734: ----------------------------------- Summary: Streams IllegalStateException in trunk during rebalance Key: KAFKA-9734 URL: https://issues.apache.org/jira/browse/KAFKA-9734 Project: Kafka Issue Type: Bug Components: streams Reporter: John Roesler Assignee: John Roesler
I have observed the following exception to kill a thread in the current trunk of Streams: {noformat} [2020-03-19 07:04:35,206] ERROR [stream-soak-test-e60443b4-aa2d-4107-abf7-ce90407cb70e-StreamThread-1] stream-thread [stream-soak-test-e60443b4-aa 2d-4107-abf7-ce90407cb70e-StreamThread-1] Encountered the following exception during processing and the thread is going to shut down: (org.apache.kafka.streams.processor.internals.StreamThread) java.lang.IllegalStateException: The changelog reader is not restoring active tasks while trying to transit to update standby tasks: {} at org.apache.kafka.streams.processor.internals.StoreChangelogReader.transitToUpdateStandby(StoreChangelogReader.java:303) at org.apache.kafka.streams.processor.internals.StreamThread.runOnce(StreamThread.java:582) at org.apache.kafka.streams.processor.internals.StreamThread.runLoop(StreamThread.java:498) at org.apache.kafka.streams.processor.internals.StreamThread.run(StreamThread.java:472){noformat} Judging from the fact that the standby tasks are reported as an empty set, I think this is just a missed case in the task manager. PR to follow shortly. -- This message was sent by Atlassian Jira (v8.3.4#803005)
