-------------------------------
HI [~Tao Jie], I think we need not have to modify some apis in
{{RmAdminProtocol}}, We could add a new api itself. If there is a clear
usecase, i think there is no issue in adding an api.
But its better we discuss more in that. Looping [[email protected]]
and [~leftnoteasy].

> Today when we add nodelabels to nodes, it would succeed even if nodes are not
> existing NodeManger in cluster without any message.
> It could be like this:
> When we use *yarn rmadmin -replaceLabelsOnNode --fail-on-unkown-nodes
> "node1=label1"* , it would be denied if node is unknown.
