Guozhang Wang commented on KAFKA-3758:
--------------------------------------
I think there may be an issue about directory locking that results in both this
and KAFKA-3752.
I will investigate further and update these tickets later.
One question: is your Kafka Streams processes running on the same node as Kafka
servers, i.e. if you shutdown some Kafka broker does that also kill some
running Kafka Streams process?
> KStream job fails to recover after Kafka broker stopped
> -------------------------------------------------------

> Key: KAFKA-3758
> URL: https://issues.apache.org/jira/browse/KAFKA-3758
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.0.0
> Reporter: Greg Fodor
> Assignee: Guozhang Wang
> Attachments: muon.log.1.gz

> We've been doing some testing of a fairly complex KStreams job and under load
> it seems the job fails to rebalance + recover if we shut down one of the
> kafka brokers. The test we were running had a 3-node kafka cluster where each
> topic had at least a replication factor of 2, and we terminated one of the
> nodes.
> Attached is the full log, the root exception seems to be contention on the
> lock on the state directory. The job continues to try to recover but throws
> errors relating to locks over and over. Restarting the job itself resolves
> the problem.
