> *Nodelabel mapping with NodeManager  is going wrong if combination of hostname and then
NodeId is used to update nodelabel mapping*
> *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
> {noformat}
