> The ApplicationMasterService currently sends a resync response to which the 
> AM responds by shutting down. The MRAppMaster behavior is expected to change 
> to calling resyncing with the RM. Resync means resetting the allocate RPC 
> sequence number to 0 and the AM should send its entire outstanding request to 
> the RM. Note that if the AM is making its first allocate call to the RM then 
> things should proceed like normal without needing a resync. The RM will 
> return all containers that have completed since the RM last synced with the 
> AM. Some container completions may be reported more than once.
