[jira] [Updated] (YARN-4925) ContainerRequest in AMRMClient, application should be able to specify nodes/racks together with nodeLabelExpression

     [ https://issues.apache.org/jira/browse/YARN-4925?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bibin A Chundatt updated YARN-4925:
-----------------------------------
    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}}

{noformat}
    // 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");
    }
{noformat}

{{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
