Sunil G commented on YARN-3216:

hi [~Naganarasimha Garla]
Option2 may come with more complexity and user may not understand that 
calculation very well. One of the reason is, if we have multiple partitions for 
queue, the resource size is also reducing per partition. And its possible that 
, even to launch one application, we may need to cross this limit totally in 
one partition OR even stop that application from launching. Yes, its more apt 
to do it, but we also have to see that how much complexity it adds. we can 
discuss more and can decide on approach by weighing the simpleness and 
correctiveness in the approach.

> Currently, max-am-resource-percentage considers default_partition only. When 
> a queue can access multiple partitions, we should be able to compute 
> max-am-resource-percentage based on that.
