Wangda Tan commented on YARN-9930:
----------------------------------
Thanks [~pbacsko], it will be make sense to create a one-pager doc and talk
about what is the behavior looks like.
For example, how this feature related to maximum-am-limit. And how refreshQueue
works with this feature (increase #running-app-limit seems fine, but how about
shrink #running-app-limit?).
