--------------------------------------
Summary: Abort if security credentials become invalid
Key: HBASE-15618
URL: https://issues.apache.org/jira/browse/HBASE-15618
Project: HBase
Issue Type: Bug
Reporter: Andrew Purtell
We are investigating a production incident where a bad keytab push seems to
have caused one regionsever, serving hot regions, to lose the ability to
communicate with clients. After the fact we see this server threw a steady
stream of GSS initiate failed errors and lingered in an unhealthy state for too
long. HBase did not automatically take any corrective action, like an abort of
the affected process, which would have recovered service without operator
intervention.
Consider detecting and aborting if security credentials like the Kerberos
keytab become invalid during runtime.
