--------------------------------------
Summary: AddNodeLabel on duplicate label addition shows success
Key: YARN-3963
URL: https://issues.apache.org/jira/browse/YARN-3963
Project: Hadoop YARN
Issue Type: Bug
Reporter: Bibin A Chundatt
Assignee: Bibin A Chundatt
Priority: Minor
Currently as per the code in {{CommonNodeLabelManager#addToClusterNodeLabels}}
when we add same nodelabel again event will not be fired so no updation is
done.
{noformat}
./yarn rmadmin –addToClusterNodeLabels x
./yarn rmadmin –addToClusterNodeLabels “x(exclusive=true)”
./yarn rmadmin –addToClusterNodeLabels “x(exclusive=false)”
{noformat}
All these commands will give success when applied through CLI again
