Arun Suresh commented on YARN-3176:
-----------------------------------
Thanks for the patch [~l201514],
The patch itself looks fine. But, currently, I see that quite a lot of queue
properties do not inherit from the parent. for eg. Min(Max)Resources,
Preemption Timeouts etc. Should we broaden the scope of the JIRA to include
these as well ?
Also, I was also thinking, is it right simply inherit the maxApp ? The queue in
question can hog all the apps and not leave its siblings any. Should we use the
queue share to determine the max apps ?
Thoughts ?

> if the child queue does not have a maxRunningApp limit, it will use the
> queueMaxAppsDefault. This behavior is not quite right, since
> queueMaxAppsDefault is normally a small number, whereas some parent queues do
> have maxRunningApp set to be more than the default
