-------------------------------------
Hi [~csexz], yes, this is a valid concern. Actually I discussed this previously
with Wangda. We will likely have to find a slightly different approach.

> Right now capacity scheduler uses UserGroupMappingPlacementRule to determine
> queue mappings. This rule stores mappings in
> {{yarn.scheduler.capacity.queue-mappings}}. For users with a large number of
> mappings, adding or removing queue mappings becomes infeasible.
> Need to come up with a way to add/remove individual mappings, for any/all
> different configured placement rules.
