[jira] Created: (MAPREDUCE-1609) TaskTracker.lcoalizeJob should not set permissions on job log directory recursively

TaskTracker.lcoalizeJob should not set permissions on job log directory recursively
-----------------------------------------------------------------------------------

                 Key: MAPREDUCE-1609
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1609
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
    Affects Versions: 0.22.0
            Reporter: Amareshwari Sriramadasu
            Assignee: Amareshwari Sriramadasu
             Fix For: 0.22.0


Currently TaskTracker.lcoalizeJob sets permissions (570 with LinuxTaskController) on job log directory recursively. When the tracker restarts/reinits, if there are new tasks for the job, localizeJob would find attempt log directories for the earlier tasks. If the job has many tasks, it would spend significant time in chmod'ing.

Also, if a cleanup attempt is launched after the restart/reinit, we would hit MAPREDUCE-1607.
