Changing permissions of files/dirs under job-work-dir may be needed sothat cleaning up of job-dir in all mapred-local-directories succeeds always

                 Key: MAPREDUCE-1422
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1422
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
            Reporter: Ravi Gummadi


After MAPREDUCE-896, if LinuxTaskController is set in config, task-controller binary is launched for changing permissions of taskAttemptDir and taskWorkDir before cleaning up of these directories sothat cleanup will be succeeded even if user had created files/dirs under taskAttemptDir or taskWorkDir with non-writable permissions. Users can't create files/dirs under job-dir directly as we set 2570 for job-dir. But as job-work-dir has 2770 permissions and user can create files/dirs under job-work-dir with non-writable permissions, Changing permissions of files/dirs under job-work-dir may be needed sothat cleaning up of job-dir in all mapred-local-directories succeeds always.
