> Currently it is very confusing to have the two configs in two different files
> (yarn-site.xml and capacity-scheduler.xml).
>
> Maybe a better approach is: we can delete the scheduling-request.allowed in
> CS, and update placement-constraints configs in yarn-site.xml a bit:
>
> - Remove placement-constraints.enabled, and add a new
> placement-constraints.handler, by default is none, and other acceptable
> values are a. external-processor (since algorithm is too generic to me), b.
> scheduler.
> - And add a new PlacementProcessor just to pass SchedulingRequest to
> scheduler without any modifications.
