Subject [jira] Created: (MAPREDUCE-1316) JobTracker holds stale references to retired jobs via speculated tips

JobTracker holds stale references to retired jobs via speculated tips 
----------------------------------------------------------------------

                 Key: MAPREDUCE-1316
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1316
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
            Reporter: Amar Kamat


JobTracker fails to remove speculative tasks' mapping from _taskToTIPMap_ if the job finishes
and retires before the tracker (running the speculative tasks) reports back. In such cases
a stale reference is held to TaskInProgress (and thus JobInProgress) long after the job is
gone leading to memory leak.
