Jian He commented on YARN-3286:
-------------------------------
I think this has changed the behavior that without any RM/NM restart features
enabled, earlier restarting a node will trigger RM to kill all the containers
on this node, but now it won't ?
> Cleanup RMNode#ReconnectNodeTransition

> RMNode#ReconnectNodeTransition has messed up for every ReconnectedEvent. This
> part of the code can be clean up where we do not require to remove node and
> add new node every time.
> Supporting to above point, in the issue discussion YARN-3222 mentioned in the
> comment

> Clean up can do the following things
> # It always remove an old node and add a new node. This is not really
> required, instead old node can be updated with new values.
> # RMNode#totalCapability has stale capability after NM is reconnected.
