---------------------------------

Thanks a lot Wangda for the clear explanation! I think YARN-4140 is what we need.

> Currently, node label expression supporting in capacity scheduler is partial completed.
Now node label expression specified in Resource Request will only respected when it specified
at ANY level. And a ResourceRequest/host with multiple node labels will make user limit, etc.
computation becomes more tricky.
> Now we need temporarily disable them, changes include,
> - AMRMClient
> - ApplicationMasterService
> - RMAdminCLI
> - CommonNodeLabelsManager
