Wangda Tan commented on YARN-2694:
----------------------------------
I think it's better to do it in a separated ticket or we will completely mix
them together.
> Ensure only single node labels specified in resource request / host, and node
> label expression only specified when resourceName=ANY

> 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
