Arpit Gupta created MAPREDUCE-5565:
--------------------------------------
Summary: job clean up fails on secure cluster as the file system
is not created in the context of the ugi running the job
Key: MAPREDUCE-5565
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5565
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobtracker
Affects Versions: 1.2.1
Reporter: Arpit Gupta
Assignee: Arun C Murthy
Priority: Critical
On secure clusters we see the following exceptions in the jt log
{code}
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)]
{code}
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.
