Craig Welch commented on YARN-796:
----------------------------------

Good, what you describe wrt the cli is what I was trying to describe, I just might not have
been very clear about it.  I'm going to go ahead then and make the changes for the service
side to match what we've described.

> It will be useful for admins to specify labels for nodes. Examples of labels are OS,
processor architecture etc.
> We should expose these labels and allow applications to specify labels on resource-requests.
> Obviously we need to support admin operations on adding/removing node labels.
