Arun C Murthy commented on YARN-796:
------------------------------------
Agree with [~tucu00] that it's better to reject RRs which ask for non-existent
labels. However, to [~djp]'s point, I think rather than rely on adding a label
in 2 places (RM & individual NM), we are better off having the RM track
existing labels dynamically (add/remove from a global list at RM as NMs
register/deregister) and reject RRs as they come in.
So, we get both benefit of strict checking and operational simplicity of having
to specify things in only one place i.e. the NM.
> 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.
