> In AM, for graceful cleanup, I propose addition of a DeletionService which will do the following :
> 1. Cleanup of failed tasks (temporary data need not occupy space till NM's Deletion Service is invoked)
> 2. Staging directory deletion (During AM shutdown, its better to place staging dir cleanup in Deletion Service: Refer to MAPREDUCE-4841 )
