      Description

      Karam Singh was executing a sleep job with 100,000 tasks on a 350 node cluster to test MR AM's scalability and ran into this. The job ran successfully but the history was not available.

      I debugged around and figured that the job is finishing prematurely before the JobHistory is written. In most of the cases, we don't see this bug as we have a 5 seconds sleep in AM towards the end.
