Sunil G commented on YARN-4855:
-------------------------------
bq.he need not worry whether the node is temporarily down and he can just apply
the label mappings
Thanks [~Naganarasimha] for the detailed clarification. This makes sense to me.
bq.How about renaming it to "--fail-on-unkown-nodes"
+1 for this as we all agree that current naming is confusing. Thanks
[~leftnoteasy] and [~Naganarasimha].

> 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 "node1=label1"*, it would be
> denied if node does not exist.
> When we use *yarn rmadmin -replaceLabelsOnNode -force "node1=label1"* would
> add nodelabels no matter whether node exists
