Siqi Li commented on YARN-2811:
-------------------------------
After I digging through the code, it seems that in 2.4 resource allocation for
reserved containers doesn't check the queue maximum any more. That's why queues
are exceeding their maximum when under a certain amount of load
> Fair Scheduler is violating max memory settings in 2.4

> Issue Type: Bug
> Affects Versions: 2.4.0
> Reporter: Siqi Li

> This has been seen on several queues showing the allocated MB going
> significantly above the max MB and it appears to have started with the 2.4
> upgrade.
