Naganarasimha G R commented on YARN-2923:
-----------------------------------------

Thanks [~john.jian.fang] for your feedback, Will check the feasibility during the review of
these 2 jiras and try to get your suggestion in, but for now  if you are trying to configure
only once then you can use RM REST API configuration for Node Labels from your controller
when adding additional nodes, Please share your opinion if you see any disadvantages in doing
so.

> As part of Distributed Node Labels configuration we need to support Node labels to be
configured in Yarn-site.xml. And on modification of Node Labels configuration in yarn-site.xml,
NM should be able to get modified Node labels from this NodeLabelsprovider service without
NM restart
