Error when running job as a different user

[Rui Shi]

Hi,

After I start the cluster as user1, I submit a job as a different user (user2) 
and get the following error. It seems that the job submitter still tries to act 
as user1 and locate the job.xml from /tmp/hadoop-user1 which does not exist. 
Anything wrong here?

Exception in thread "main" org.apache.hadoop.ipc.RemoteException: 
java.io.IOException: 
/tmp/hadoop-user1/mapred/system/job_200805292307_0001/job.xml: No such file or
