Vinod Kumar Vavilapalli commented on YARN-3345:

Just looked at this. I think UpdateNodeLabels can be used to also change the 
exclusivity of an existing label - which may or may not be something that is a 
real use-case. I think we should have the APIs to create labels with the right 
properties at creation time itself.

> Add non-exclusive node label API to RMAdmin protocol and NodeLabelsManager
