[~Naganarasimha]Thanks for your explaination, I know this. In our modification, we doesn't
consider the lables as a resource pool, so we didn't set the resource for label. So we open
the multi-nodelabel.

> 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
