Wangda Tan commented on YARN-4106:
----------------------------------

[~Naganarasimha], I think do the sync on periodic intervals seems reasonable to 
me. 

Maybe we can do this: when a label is not accepted by RM, it will retry every 
fetch-interval. If a label is accepted by RM, it won't resend unless labels 
updated in the node.

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