Steve Loughran commented on HADOOP-10036:
-----------------------------------------
... better: have {{SaslRpcClient.getServerPrincipal()}} raise a specific
exception for for an invalid (and irreconcilable) auth configuration problem
which retrying will have no effect whatsoever -there are four possible causes
of this.
> RetryInvocationHandler should recognise that there is no point retrying to
> auth failures

> Key: HADOOP-10036
> URL: https://issues.apache.org/jira/browse/HADOOP-10036
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ipc
> Affects Versions: 2.2.1
> Reporter: Steve Loughran
> Priority: Minor
>
> The {{RetryInvocationHandler}} tries to retry connections, so as to handle
> transient failures.
> However, auth failures aren't treated as special, so it spins even though the
> operation will not succeed with the current configuration
