> Tasktracker is holdingup TaskStatus objects in runningTasks forever in somecases. This happens in the following scenario.
> -> Task got an exception
> -> Sets the phase to CLEANUP
> -> The task tries to do cleanup. and it doesn't respond after that.
> -> TaskTracker marks the task unresponsive and makes the task FAILED_UNCLEAN
> -> TaskTracker doesn't remove it from runningTasks data structure, since phase is CLEANUP and state is FAILED_UNCLEAN (it treats this as cleanupAttempt).
> I would propose that once the task goes to CLEANUP phase, kill on the task should mark it a clean failure i.e. The task state should be FAILED/KILLED.
