I'm using Accumulo 1.7.0 and finding that after some period of time (>8 hours, <3 days - happened over the weekend) my ingest fails with errors regarding "Failed to find any Kerberos tgt". My guess is that the ticket from the keytab has expired, and needs to be renewed - from memory, I had seen a Kerberos tgt renewer thread running in my client, so assumed it happened automagically. Is that the case? Perhaps I am hitting this bug? https://issues.apache.org/jira/browse/ACCUMULO-4069
Thanks, James
