Fixed review comments * Fixed review comments * Commenting out a test instead of fixing it as it going to be deleted in the near future.
Testing done * Killed RM while running a long running job. RM got relaunched on amother node and was able to recover state from state store successfully. FGS resumed successfully. Job completed successfully. * Killed zero profile NM. Saw containers and corresponding mesos tasks being lost. NM was relaunched and FGS resumed successfully.
