------------------------------------
    Attachment: YARN-4855.008.patch

Thanks for working on the review comments [~Tao Jie], 
I have uploaded patch for following items :
# {{acceptNode}} was not fitting hence made it {{isNodeSame}}
# ??"./yarn rmadmin \-replaceLabelsOnNode"?? : sorry my bad, it was going wrong when *--fail-on-unkown-nodes*
followed with no args
# ??I will trying to refine here, if you know some best practices, please tell me?? :   Have
corrected in the attached, Please take a look.

please verify whether my patch is fine.

> 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.
