Subject [jira] [Created] (HADOOP-13604) Abort retry loop when RPC has an unrecoverable error

---------------------------------------

             Summary: Abort retry loop when RPC has an unrecoverable error
                 Key: HADOOP-13604
                 URL: https://issues.apache.org/jira/browse/HADOOP-13604
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Henry Robinson


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.
