> Kerberos tickets are not being renewed by Hadoop

> Issue Type: Bug

>
> I've discovered after some time of having kerberos enabled processors, that
> the kerberos ticket is not being renewed as it should. This is strange
> because according to HADOOP-6656, this should be automatically taken care of
> with a utility thread. I examined the NiFi jstack and saw that the renewal
> thread was present, so I'm not sure what's going on.
> Does NiFi do something with the processor threads that cause child threads to
> suspend? I have a patch that I'm currently testing (currently looking good),
> that will renew the kerberos ticket on getFileSystem() if a threshold is
> reached (e.g. 4 hours).
