Subject [jira] Created: (HADOOP-639) task cleanup messages can get lost, causing task trackers to keep tasks forever
Date Wed, 25 Oct 2006 22:03:16 GMT
task cleanup messages can get lost, causing task trackers to keep tasks forever
-------------------------------------------------------------------------------

                 Key: HADOOP-639
                 URL: http://issues.apache.org/jira/browse/HADOOP-639
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.7.2
            Reporter: Owen O'Malley
         Assigned To: Owen O'Malley
             Fix For: 0.8.0


If the pollForTaskWithClosedJob call from a job tracker to a task tracker times out when a
job completes, the tasks are never cleaned up. This can cause the mini m/r cluster to hang
on shutdown, but also is a resource leak.
