Wangda Tan commented on YARN-9206:
----------------------------------

[~kshukla], could u please add a method to NodeState such as "isInactiveState" for easier
maintenance? 

+ [~suma.shivaprasad] could you please help to get this patch committed?

> This should include SHUTDOWN state as they are inactive too. This method is used for
node reports and such so might be useful to account for them as well.
