sandflee commented on YARN-4138:
--------------------------------

to simple the race condition process, could we reject the increase/decrease request if a increase
notifiy is not sended by NM?

> In YARN-1651, after container resource increase token expires, the running container
is killed.
> This ticket will change the behavior such that when a container resource increase token
expires, the resource allocation of the container will be reverted back to the value before
the increase.
