----------------------------------
Summary: Kerberos tickets are not being renewed by Hadoop
Key: NIFI-997
URL: https://issues.apache.org/jira/browse/NIFI-997
Project: Apache NiFi
Issue Type: Bug
Reporter: Ricky Saltzer
Assignee: Ricky Saltzer
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).
