Wangda Tan commented on YARN-2786:
----------------------------------

[~sunilg],
Thanks for this comment, 
For 
1) I totally agree it is a very useful API, but we don't have such support in REST API and
web UI, let's just keep it consistent :)
2) Good suggestion, will include it in patch now working on if nobody against :)

> With YARN-2778, we can list node labels on existing RM nodes. But it is not enough, we
should be able to: 
> 1) list node labels collection 
> 2) list node-to-label mappings even if the node hasn't registered to RM.
> The command should start with "yarn node-labels ..."
