Jian He commented on YARN-2209:
-------------------------------
bq. The customized AM code could get RESYNC from response previously (like what
we original do in AMRMClient) to handle AM re-registering case.
Previously, AM doesn't do re-register. Re-register on RM restart is a new
requirement coming out from YARN-556
> Replace AM resync/shutdown command with corresponding exceptions
