[jira] [Commented] (KAFKA-3409) Mirror maker hangs indefinitely due
to commit
[ https://issues.apache.org/jira/browse/KAFKA-3409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15197729#comment-15197729 ]
Ashish K Singh commented on KAFKA-3409:
---------------------------------------
This can happen if consumer rebalance is in progress. Offsets must have already been committed during onPartitionsRevoked event handling. Would it be fair to simply swallow this exception?
[~becket_qin] thoughts?

> Mirror maker hangs indefinitely upon receiving CommitFailedException. I believe this is due to CommitFailedException not caught by mirror maker and mirror maker has no way to recover from it.
