Andras Gyori commented on YARN-10623:
-------------------------------------
Thank you [~zhuqi] for the patch. Could you elaborate on the necessity of this
feature please? Refreshing a queue only makes sense when you change them, and
this is already implemented when mutating queue properties via the mutation
API. Additionally, I think this is a non-negligible performance hit on the
scheduler and I think there should be a well founded reason to do it.
> Capacity scheduler should support refresh queue automatically by a thread
> policy.
