Allen Wittenauer commented on YARN-796:
---------------------------------------

Then let me be more blunt about it:

I'm -1 this patch if I can't do dynamic labels from the node manager via a script.

> 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.
