Metrics from the TaskTracker are updated only when map/reduce tasks start/end/fail
----------------------------------------------------------------------------------

                 Key: HADOOP-1446
                 URL: https://issues.apache.org/jira/browse/HADOOP-1446
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.12.3
            Reporter: Devaraj Das
            Assignee: Devaraj Das
             Fix For: 0.14.0


Metrics reporting from the TaskTracker for the maps_running and reduces_running metrics are
done only when a task is starting up or finishing up. This is wrong and the metrics reporting
should be done periodically during the life of the TaskTracker just as it is done for the
JobTracker case.
