> Project: HBase
> Issue Type: Bug
> Reporter: Andrew Purtell
> Assignee: churro morales
>
> 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 a steady stream of GSS
> initiation failure messages in the logs. The affected regionserver 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.
