> 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.
