Description

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.
