JobTracker should not try to promote a (map) task if it dis not write to DFS at all
-----------------------------------------------------------------------------------

                 Key: HADOOP-3140
                 URL: https://issues.apache.org/jira/browse/HADOOP-3140
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Runping Qi



In most cases, map tasks do not write to dfs.
Thus, when they complete, they should not be put into commit_pending queue at all.
This will improve the task promotion significantly.
