----------------------------------
Resolution: Not A Problem
> Capture org.apache.kafka.clients.consumer.CommitFailedException in
> UncaughtExceptionHandler
> -------------------------------------------------------------------------------------------
>
> Key: KAFKA-3523
> URL: https://issues.apache.org/jira/browse/KAFKA-3523
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: Guozhang Wang
> Assignee: Eno Thereska
> Labels: newbie, user-experience
> Fix For: 0.10.0.0
>
>
> When the sync commit failed due to an ongoing rebalance, it is thrown all the
> way up to the main thread and cause the whole Kafka Streams application to
> stop, even if users set UncaughtExceptionHandler. We need to be able to catch
> this exception in that handler as well.
> Example stack trace (with UncaughtExceptionHandler set, but not been able to
> capture this exception):
> {code}
> [2016-04-06 17:49:33,891] WARN Failed to commit StreamTask #0_0 in thread
> [StreamThread-1]:
> (org.apache.kafka.streams.processor.internals.StreamThread:485)
> org.apache.kafka.clients.consumer.CommitFailedException: Commit cannot be
> completed since the group has already rebalanced and assigned the partitions
> to another member. This means that the time between subsequent calls to
> poll() was longer than the configured session.timeout.ms, which typically
> implies that the poll loop is spending too much time message processing. You
> can address this either by increasing the session timeout or by reducing the
> maximum size of batches returned in poll() with max.poll.records.
