--------------------------------------
Assignee: Matthias J. Sax
> Improve exception handling on coordinator interactions
> ------------------------------------------------------
>
> Key: KAFKA-5313
> URL: https://issues.apache.org/jira/browse/KAFKA-5313
> Project: Kafka
> Issue Type: Sub-task
> Components: streams
> Affects Versions: 0.11.0.0
> Reporter: Eno Thereska
> Assignee: Matthias J. Sax
> Fix For: 1.0.0
>
>
> Exceptions during assignment of tasks are caught in ConsumerCoordinator.java
> and streams becomes aware of them during the
> StreamThread.onPartitionsAssigned() and StreamThread.onPartitionsRevoked()
> methods. Eventually these exceptions go through StreamThread.pollRequests()
> all the way up to StreamThread.runLoop() and will halt the stream thread that
> is processing these exceptions. Other stream threads may continue processing,
> however it is likely they will experience problems too soon after.
> Exceptions here include LockExceptions that are thrown if tasks cannot use a
> particular directory due to previous tasks not releasing locks on them during
> reassignment.
