Hari Sekhon commented on YARN-3638:

Sorry the wording of these fields is sub-optimal, I meant to say the "Used 
Capacity" of the "Absolute Capacity" [configured] is what's shown, and I'd like 
"Absolute Used Capacity" to be shown to the right of the horizontal bars.

It would make more intuitive sense to show that 50% of the total cluster is 
being used by a given queue than that the currently shown "Used Capacity" of 
150% of what that queue had configured as dedicated capacity. In any event, 
both can be shown so you can see at a glance what's being used out of the total 
cluster between the queues, as well as how much over the dedicated capacity the 
queue is consuming (which is what's currently shown).

>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: capacityscheduler, resourcemanager, scheduler, yarn
>    Affects Versions: 2.6.0
>         Environment: HDP 2.2
>            Reporter: Hari Sekhon
>            Priority: Minor
> Request to show % of total cluster resources each queue is currently 
> consuming for jobs on the Yarn Resource Manager Scheduler page.
> Currently the Yarn Resource Manager Scheduler page shows the % of total used 
> for root queue and the % of each given queue's configured capacity that is 
> used (often showing say 150% if the max capacity is greater than configured 
> capacity to allow bursting where there are free resources). This is fine, but 
> it would be good to additionally show the % of total cluster that each given 
> queue is consuming and not just the % of that queue's configured capacity.
