             Summary: NM to nodelabel mapping going wrong after RM restart
                 Key: YARN-4454
                 URL: https://issues.apache.org/jira/browse/YARN-4454
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bibin A Chundatt
            Assignee: Bibin A Chundatt
            Priority: Critical


*Steps to reproduce*

1.Create cluster with 2 NM
2.Add label X,Y to cluster
3.replace  Label of node  1 using <HOSTNAME1:PORT>,x
4.replace label for node 1 by <HOSTNAME1>,y
5.Again replace label of node 1 by <HOSTNAME1:PORT>,x

Check cluster label mapping HOSTNAME1 will be mapped with X 

Now restart RM 2 times NODE LABEL mapping of HOSTNAME1:PORT changes to Y
