Wangda Tan commented on YARN-796:
---------------------------------

Hi [~yufeldman],
Thanks for your support on this,
I've assigned some JIRAs to myself because I've patches for them already (they're parts of
big patch I uploaded today), just wait for some former JIRAs get committed and I'll split
and upload.

Please feel free to add JIRAs with no assignee to yourself if you feel interested. And I believe
there're more tasks/improvements we can do for YARN-796, please create new tasks if you have
any ideas :)

Many thanks,
Wangda

> 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.
