Subject [jira] Created: (MAPREDUCE-2217) The expire launching task should cover the UNASSIGNED task
Date Tue, 14 Dec 2010 00:20:01 GMT
The expire launching task should cover the UNASSIGNED task
----------------------------------------------------------

                 Key: MAPREDUCE-2217
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2217
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobtracker
    Affects Versions: 0.23.0
            Reporter: Scott Chen
            Assignee: Scott Chen
             Fix For: 0.23.0


The ExpireLaunchingTask thread kills the task that are scheduled but not responded.
Currently if a task is scheduled on tasktracker and for some reason tasktracker cannot put
it to RUNNING.
The task will just hang in the UNASSIGNED status and JobTracker will keep waiting for it.

JobTracker.ExpireLaunchingTask should be able to kill this task.
