> Currently, the SchedulingPlacementSet is very confusing. Here're its
> responsibilities:
> 1) Store ResourceRequests. (Or SchedulingRequest after YARN-6592).
> 2) Decide order of nodes to allocate when there're multiple node candidates.
> 3) Decide if we should reject node for given requests.
> 4) Store any states/cache can help make decision for #2/#3
