Description

On secure clusters we see the following exceptions in the jt log

2013-10-04 04:52:31,753 ERROR org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:tt/host@REALM cause:javax.security.sasl.SaslException: GSS
initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]

And after the job finishes the staging dir is not cleaned up. While debugging with acmurthy we determined that file system object needs to be created in the the context of the user who ran the job.

Job however successfully completes
