Allen Wittenauer commented on YARN-796:
---------------------------------------
I might have missed it, but I don't see dynamic labels generated from an admin
provided script or class on the NM listed above. That's a must have feature to
make this viable for any large installation.
> Allow for (admin) labels on nodes and resource-requests

> 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.
