Wangda Tan commented on YARN-3216:
----------------------------------

Hi [~sunilg],

I think the changes to AbstractCSQueue may not be necessary, could you take a 
look at my previous comment (copied here) and let me know your thoughts?
bq. AbstractCSQueue: Instead of adding AM-used-resource to parentQueue, I think 
we may only need to calculate AM-used-resource on LeafQueueu and user. 
Currently we don't have limitation of AM-used-resource on parentQueue, so the 
aggregated resource may not be very useful. We can add it along the hierachy if 
we want to limit max-am-percent on parentQueue in the future.

If max-am-percent for queue-partitions isn't set, I think it should use 
queue.max-am-percent instead of 0 to avoid painful of configuration. (admin has 
to set max-am-percent after add a new partition)

I found the logic in your patch is: if max-am-percent for partition-x is not 
set, partition-x's am-limit equals to default-partition's am-limit, which is 
not correct to me. am-limit under each partition should be calculated 
independently, since total resource for different partitions varies.

If you agree, could you merge the am-limit computation logic of default 
partition and specific partition?

Thoughts?

Thanks,

> 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.
