                 Key: MAPREDUCE-1559
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1559
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions: 0.22.0
            Reporter: Devaraj Das
            Assignee: Devaraj Das
             Fix For: 0.22.0


The submitJob RPC finally creates a timer task for renewing the delegation tokens of the submitting user. This timer task inherits the context of the RPC handler that runs in the context of the job submitting user, and when it tries to create a filesystem, the RPC client tries to use the user's credentials. This should instead use the JobTracker's credentials.
