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

Thanks for raising this issue [~bibinchundatt],
This issue is happening because we are trying to avoid sending labels everytime 
to RM as if sent everytime RM needs to validate it and refresh the Label 
mapping for each Node's HB and its a unnecessary overload @ RM side. 
So only  in this failure case, wherein the Labels are not accepted by RM then 
may be we can send the labels as part of each HB (or on periodic intervals) 
send the labels from NM to RM . Thoughts ? cc/ [~leftnoteasy]

> NodeLabels for NM in distributed mode is not updated even after 
> clusterNodelabel addition in RM

> NodeLabels for NM in distributed mode is not updated even after 
> clusterNodelabel addition in RM
> Steps to reproduce
> ===============
> # Configure nodelabel in distributed mode
> yarn.node-labels.configuration-type=distributed
> provider = config
> yarn.nodemanager.node-labels.provider.fetch-interval-ms=120000ms
> # Start RM the NM
> # Once NM is registration is done add nodelabels in RM
> Nodelabels not getting updated in RM side
