-----------------------------------

             Summary: The -addToClusterNodeLabels command doesn't provides 
error message for invalid node ID
                 Key: YARN-8021
                 URL: https://issues.apache.org/jira/browse/YARN-8021
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Gergely Novák


{noformat}
yarn rmadmin -replaceLabelsOnNode "invalid-node-id:1234=node_label_x"
{noformat}

The above command doesn't return anything aside from the usual "Connecting to 
ResourceManager at..." message. It also doesn't print anything for a successful 
node label replacement, but it does throw an error for most of the other bad 
inputs (invalid port, invalid node label, invalid format).
