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.
