    Description

      Currently with nodelabel AMRMClient will not be able to specify nodelabels with Node/Rack requests.For application like spark NODE_LOCAL requests cannot be asked with label expression.
      As per the check in AMRMClientImpl#checkNodeLabelExpression

          // Don't allow specify node label against ANY request
          if ((containerRequest.getRacks() != null && 
              (!containerRequest.getRacks().isEmpty()))
              || 
              (containerRequest.getNodes() != null && 
              (!containerRequest.getNodes().isEmpty()))) {
            throw new InvalidContainerRequestException(
                "Cannot specify node label with rack and node");
          }
      

      AppSchedulingInfo#updateResourceRequests we do reset of labels to that of OFF-SWITCH.

      The above check is not required for ContainerRequest ask /cc wangda thank you for confirming
