Jian He updated YARN-2249:
--------------------------
Description: AM resync on RM restart will send outstanding container
release requests back to the new RM. In the meantime, NMs report the container
statuses back to RM to recover the containers. If RM receives the container
release request before the container is actually recovered in scheduler, the
container won't be released and the release request will be lost. (was: AM
resync on RM restart will send outstanding resource requests, container release
list etc. back to the new RM. It is possible that RM receives the container
release request before the container is actually recovered. )
> RM may receive container release request on AM resync before container is
> actually recovered
