Hi [~gp.leftnoteasy]

{code}
    AddToClusterNodeLabelsResponse response =
           
recordFactory.newRecordInstance(AddToClusterNodeLabelsResponse.class);
    try {
        
rmContext.getNodeLabelManager().addToCluserNodeLabels(request.getNodeLabels());
        RMAuditLogger
          .logSuccess(user.getShortUserName(), argName, "AdminService");
        return response;
    }
{code}


Here *response* object is created. Now labels which u received from incoming 
request is passed to LabelManager and it may undergo a validation there. If any 
problem of invalid label arises, how response object is populated. Here I was 
not able to get that part of code.
