Wangda Tan commented on YARN-796:
---------------------------------
[~acmurthy], thanks for this patch, I’ve a few questions/suggestions for this
implementation. Please forgive the ignorance if my suggestion makes no sense.
1. Is it good to put SchedulerLabelsManager.add/removeNode invoke to RMNodeImpl
transition, which can be leveraged by CS/FS at the same time?
2. I’m wondering does it make sense to put SchedulerLabelsManager into
RMContext?
3. Do we need consider labels of queue/application (not RR) will affect
headroom of an application? (If yes, we need consider linking this to
YARN-1198).
Thanks,
> 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.
