Jian He commented on YARN-917:
------------------------------
The above solution looks good. thinking another way: Does it make sense just to
move "addService(createStagingDirCleaningService());" before
"addIfService(containerAllocator);" inside MRAppMaster ? In this way, when MR
stops, cleanup staging dir will be called after unregister. This looks simpler.
> Job can fail when RM restarts after staging dir is cleaned but before MR
> successfully unregister with RM
