NIFI-3574 - PutHiveStreaming UGI fixes
----
> PutHiveStreaming affected by UserGroupInformation static side effects
> ----------------------------------------------------------------------
>
> Key: NIFI-3574
> URL: https://issues.apache.org/jira/browse/NIFI-3574
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Bryan Rosander
> Assignee: Bryan Rosander
>
> Currently if you point a PutHiveStreaming processor at a secure cluster,
> start it, stop it, and then reconfigure it to point at a different unsecured
> cluster, some state from the first connection is used by the underlying Hive
> and Hadoop libraries when attempting to connect to the second cluster.
> This can be mitigated by ensuring that the
> UserGroupInformation.setConfiguration() method is used in onSetup() and that
> the approprate UserGroupInformation instance is used in ugi.doAs calls.
> In order to isolate multiple PutHiveStreaming processors, a
> RequiresInstanceClassLoading annotation should be added to the processor.
> This should insulate it from other static side effects.
