-----------------------------------------------
bq. c) I realize neither of you were there when we ran HOD and dealt with
Torque where a normal course of action was to just delete the configuration and
start it over because the label configuration was completely unmanageable. I
also recognize that my -1 on this "feature" is falling on deaf ears and you're
going to get this in come hell or high water.
By the time I started on HOD, those experiments were presumably over, so I
never heard about them.
IAC, the crux of what you want is a per node script based configuration. That
IS happening as we speak as part of the tickets I referred to. Further, you
don't want a central list of valid labels which I disagree with. But sure, we
will make this configurable to or not to require a central list so that you can
turn it off. Others like me can turn it on to avoid
random-labels-bubbling-up-in-my-cluster madness.

> With YARN-2778, we can list node labels on existing RM nodes. But it is not
> enough, we should be able to:
> 1) list node labels collection
> The command should start with "yarn cluster ...", in the future, we can add
> more functionality to the "yarnClusterCLI"
