sandflee commented on YARN-4051:
--------------------------------
Is it possible for the finish application or complete container requests to
arrive at this point?
yes, we see this in YARN-4050. If we register to RM after complete container
recover, we must face the risk that the container running on this node will be
killed if container recovery takes much more time(in YARN-4050), for
long-runing-services, maybe not so perfect.
> ContainerKillEvent is lost when container is In New State and is recovering

> state, when we finish application, the container still alive even after NM
> event dispatcher is unblocked.
