> 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 (fair, capacity, fifo and so on) for any queue consistently. The proposal
tries to solve many other issues in current YARN scheduling framework as well.
> Two new proposed scheduling policies YARN-3807 & YARN-3808 are based on generic scheduling
framework brought up in this proposal.
