Xianyin Xin commented on YARN-3652:
-----------------------------------
Thanks for your comments, [~vvasudev].
I agree with you on the general idea of the relation between ScheduerMetrics
and SchedulerHealth. However, SchedulerHealth now has only be implemented on
CS, if we turn to use SchedulerHealth in YARN-3630, we need to wait
SchedulerHealth support in Fair, and expose {{getSchedulerHealth}} in
YarnScheduler. Do we have any plan on that?
> A SchedulerMetrics may be need for evaluating the scheduler's performance

> As discussed in YARN-3630, a {{SchedulerMetrics}} may be need for evaluating
> the scheduler's performance. The performance indexes includes #events waiting
> for being handled by scheduler, the throughput, the scheduling delay and/or
> other indicators.
