> As I mentioned on YARN-6599, we will add SchedulingRequest as part of the PlacementConstraintUtil
method and both of processor/scheduler implementation will use the same logic. The logic looks
like:
> {code:java}
> PlacementConstraint pc = schedulingRequest.getPlacementConstraint();
> If (pc == null) {
>   pc = PlacementConstraintMgr.getPlacementConstraint(schedulingRequest.getAllocationTags());
> }
> // Do placement constraint match ...{code}
