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 ?
