Joseph Witt commented on NIFI-1722:
-----------------------------------
is this being worked or should it be moved off 0.7.0?
> Intermittent deadlocks in Kafka API when when stopping GetKafka
> ---------------------------------------------------------------

> Key: NIFI-1722
> URL: https://issues.apache.org/jira/browse/NIFI-1722
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Oleg Zhurakousky
> Assignee: Oleg Zhurakousky
> Fix For: 0.7.0

>
> It appears that Kafka gets in the state of deadlock when
> _ConsumerConnector.commitOffsets(..)_ is executed during stop call in
> GetKafka. Looking at the thread dump it may be related to the fact that we
> are shutting down consumer when onTrigger is still executing. But It also
> appears that onTrigger is in the deadlock state as well.
