Tsuyoshi Ozawa commented on YARN-2336:
--------------------------------------
[~ajisakaa] thank you for updating. Let me confirm one point. What do you think
about the null value of "childQueues" when queue doesn't exist? We have an
option to return empty hash, {}, or array, []. Currently, "users", another
collection field which can be returned in RM's RESTful API, returns null. In
the context, the behaviour of your patch looks consistent to me. This is just a
confirmation.
