[jira] [Commented] (KAFKA-4979) Handcrafted JoinGroupRequest makes
consumers on the same group to exit abruptly
[ https://issues.apache.org/jira/browse/KAFKA-4979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15968803#comment-15968803 ]
Dan commented on KAFKA-4979:
----------------------------
How is the JoinGroupRequest Handcrafted?
> Handcrafted JoinGroupRequest makes consumers on the same group to exit abruptly
> -------------------------------------------------------------------------------
>
> Key: KAFKA-4979
> URL: https://issues.apache.org/jira/browse/KAFKA-4979
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.10.2.0
> Reporter: Nacho Munoz
> Priority: Minor
>
> Given an application with a consumer group X it is possible to make the application crash by creating a bad JoinGroupRequest for the same group. I don't know if that is the expected behaviour but I think that, maybe, this could return an error and leave the application unaffected by the rogue request. Please let me know if you need any further information or if I can do anything to help.
