> Key: KAFKA-5625
> URL: https://issues.apache.org/jira/browse/KAFKA-5625
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.11.0.0
> Reporter: Xavier Léauté
> Priority: Minor
>
> I was able to cause my streams app to crash with the following error when
> attempting to join the same consumer group with a rogue client.
> At the very least I would expect streams to throw a
> {{TaskAssignmentException}} to indicate invalid subscription data.
