Review Comment:
Indeed, because it will only be used after YARN-11000, it is just easier to
see this patch in isolation (as it is already a huge one).
> Centralize queue resource calculation based on CapacityVectors

> Key: YARN-10965
> URL: https://issues.apache.org/jira/browse/YARN-10965
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacity scheduler
> Reporter: Andras Gyori
> Assignee: Andras Gyori
> Priority: Major
> Labels: pull-request-available
> Time Spent: 6.5h
> Remaining Estimate: 0h
>
> With the introduction of YARN-10930 it is possible to unify queue resource
> calculation. In order to narrow down the scope of this patch, the base system
> is implemented here, without refactoring the existing resource calculation in
> updateClusterResource (which will be done in YARN-11000).
