Description

In DAGImpl there is reference to stagingDir which has likely come in from MR. There should be no reason to have a dependency on some staging dir in the DAG AM.

      String user =
        UserGroupInformation.getCurrentUser().getShortUserName();
      Path path = DAGApps.getStagingAreaDir(job.conf, user);
      if(LOG.isDebugEnabled()) {
        LOG.debug("startJobs: parent=" + path + " child=" + dagIdString);
      }
