TAO XIAO commented on KAFKA-3409:
---------------------------------
This can also happen when producer is slow and buffer memory is full which
results in blocking consumer from polling therefore session times out. Next
time consumer calls commit or poll it has been kicked out of the group. In this
case it has no chance to call commit in onPartitionsRevoked and the consumed
offset is lost which subsequently introduces message duplication.

> Key: KAFKA-3409
> URL: https://issues.apache.org/jira/browse/KAFKA-3409
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Affects Versions: 0.9.0.1
> Environment: Kafka 0.9.0.1
> Reporter: TAO XIAO
>
> 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.
> A better approach will be catching the exception and rejoin the group. Here
> is the stack trace
