---------------------------------------
Summary: IPC retry policies should recognise that SASL auth
failures are unrecoverable
Key: HADOOP-12697
URL: https://issues.apache.org/jira/browse/HADOOP-12697
Project: Hadoop Common
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
SLIDER-1050 shows that if you don't have the right kerberos settings, the Yarn
client IPC channel blocks retrying to the talk to the RM, retrying repeatedly

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
