>          Issue Type: Bug
>          Components: ipc
>    Affects Versions: 2.7.1
>         Environment: Cluster with kerberos on and client not calling with the right credentials
>            Reporter: Steve Loughran
>            Priority: Minor

> 2016-01-07 02:50:45,111 [main] WARN  ipc.Client - Exception encountered while connecting
to the server :
>  javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException:
>  No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]
> {noformat}
> SASL exceptions need to be recognised as irreconcilable authentication failures, rather
than generic IOEs that might go away if you retry
