Wangda Tan updated YARN-796:

    Attachment: Node-labels-Requirements-Design-doc-V2.pdf

We've been carefully thinking about our requirements, the discussion from the community and
also the approach outlined in your design document. We have attempted to consolidate them
and put them together to a new design doc. We believe this proposal addresses the core use
cases listed for this feature and is also implementable in a phased timely manner. I want
to work with you to consolidate the APIs proposed to get this feature to completion soon.
Please kindly review and comment on the design when you get a chance.

> 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.
