Subject [jira] Created: (MAPREDUCE-1246) JobTrackerStatistics/JobTrackerInstrumentation counts will be incorrect if a live tracker is restarted on the same port
Date Fri, 27 Nov 2009 10:45:39 GMT
JobTrackerStatistics/JobTrackerInstrumentation counts will be incorrect if a live tracker is
restarted on the same port
-----------------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-1246
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1246
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
            Reporter: Amar Kamat


Consider a case where an active tracker is restarted and the tracker restarts on the same
port. In such a case the jobtracker we will invoke JobTracker.loseTracker() from processHeartbeat().
Later on the tracker is added back (addNewTracker()) which will update the metrics and instrumentation.
But the problem is that when the old tracker is lost the metric/instrumentation counts are
not accounted for.
