Wei Shao commented on YARN-3806:
--------------------------------
One more comment :)
Regarding YARN-3318. Yes, this proposal also proposed a general scheduling
interface by which specific policies(like fair/capacity) can work within the
scheduling framework. The interface provides ordering polices, etc., and should
be implemented by specific policies.

> Currently, a typical YARN cluster runs many different kinds of applications:
> production applications, ad hoc user applications, long running services and
> so on. Different YARN scheduling policies may be suitable for different
> applications. For example, capacity scheduling can manage production
> applications well since application can get guaranteed resource share, fair
> scheduling can manage ad hoc user applications well since it can enforce
> fairness among users. However, current YARN scheduling framework doesn’t have
> a mechanism for multiple scheduling policies work hierarchically in one
> cluster.
> YARN-3306 talked about many issues of today’s YARN scheduling framework, and
> proposed a per-queue policy driven framework. In detail, it supported
> different scheduling policies for leaf queues. However, support of different
> scheduling policies for upper level queues is not seriously considered yet.
> A generic scheduling framework is proposed here to address these limitations.
> It supports different policies for any queue consistently. The proposal tries
> to solve many other issues in current YARN scheduling framework as well.
