-----------------------------------------
Thank you for volunteering: created HADOOP-13627 for you
Bear in mind we are all scared of the code and changes breaking things; keep
the diffs minimal, and don't change the text messages we have today. Not
because they are good, but because they are searchable in existing JIRAs and
Stack Overflow topics
> Abort retry loop when RPC has an unrecoverable Auth error
> ---------------------------------------------------------
>
> Key: HADOOP-13604
> URL: https://issues.apache.org/jira/browse/HADOOP-13604
> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: Henry Robinson
> Assignee: Xiao Chen
>
> I've seen an issue where, after an RPC client hit an error obtaining a TGT
> from Kerberos, the RPC client continues to retry even though there's no
> chance of success (the no login window is set to 600s).
> In this particular deployment, the client retries 15 times at 15s intervals,
> leading to a delay of more than three minutes before the failure is bubbled
> up to the client when the RPC ultimately fails.
> Unrecoverable errors (like failures to login to Kerberos) should lead to fast
> aborts of the retry loop.
