+1 LGTM, looks like it will work like a barrier sync, the first one in will
relogin if necessary, the rest will no-op, which means there won't be a race
condition / threading issue when some of the threads call doAs. Thanks for the
improvement! Merging to master
> NiFi can encounter "no TGT" after Hive service outage
> -----------------------------------------------------

> Key: NIFI-5134
> URL: https://issues.apache.org/jira/browse/NIFI-5134
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.6.0
> Reporter: Jeff Storck
> Assignee: Jeff Storck
> Priority: Major
>
> NiFi's Hive controller service may encounter a "no TGT" error after an outage
> in Hive has occurred. The "no TGT" error can occur after the service has
> been restarted and the current TGT has expired. The Hive client/thrift does
> not seem to handle this case implicitly.
