Wangda Tan commented on YARN-796:
---------------------------------
I'm not sure what's the purpose of adding a new API to scheduler interface. I
think this proposal is a specific enhancement instead of global design
discussion, I suggest you can file a ticket under YARN-2492 and we can move
discussions to the new JIRA.
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.
