Carlo Curino commented on YARN-6528:
------------------------------------
hi [~seanpo03] thanks for the updated patch.
Regarding (3): I think the roll-up at "root" level should provide what you have
as a global metric, correct? The cost of storing is a little hire, but since
our hierarchies are usually not too deep, shouldn't be too bad.
Regarding (4): I understand, but again, I would like to see it group-by queue,
as I think this provides better visibility.
I would encourage you to take YARN-6528 and "merge" it with your effort, we can
mark one of the two patches as duplicate. Basically I would follow the
structure of YARN-6528 for queue-level metrics, but use your more rich set of
metrics to track.
Does this make sense?

> YARN-1051 introduced a ReservationSytem that enables the YARN RM to handle
> time explicitly, i.e. users can now "reserve" capacity ahead of time which is
> predictably allocated to them. In order to understand in finer detail the
> performance of Rayon, YARN-6528 proposes to include JMX metrics in the Plan
> Follower, Agent Placement and Plan Operations components of Rayon.
