----------------------------------
Summary: AbstractKerberosUser should check if ticket is renewable
Key: NIFI-11604
URL: https://issues.apache.org/jira/browse/NIFI-11604
Project: Apache NiFi
Issue Type: Improvement
Reporter: Bryan Bende
Assignee: Bryan Bende
Currently the checkTgtAndRelogin method assumes all tickets are renewable and
will attempt to call refresh() on the KerberosTicket when reaching > 80% of the
ticket lifetime. If the ticket is not renewable the refresh will fail and it
will do a full logout/login, same as if the ticket was no longer renewable, but
it could be handled more gracefully by not even calling refresh when knowing it
won't work.
