---------------------------------------
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.
