Bikas Saha commented on YARN-796:
---------------------------------
Thanks [~john.jian.fang] An interesting use case from your comment is that not
only can labels be used to specify affinity but they can be used to specify
anti-affinity ie. dont place task on a certain label.
Do I correctly understand as this being your use case?
OR
Is your ask that node managers should specify their own labels when they
register with the RM instead of the node manager to label mapping being a
central RM configuration?
> 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.
