[jira] [Commented] (MAPREDUCE-3816) capacity scheduler web ui bar graphs for used capacity wrong

Thomas Graves commented on MAPREDUCE-3816:
------------------------------------------

after thinking about this more. I changed the bar graphs to use the absolute capacities rather then the relative capacity/max capacity. The reason is that max capacity is not relative to capacity so having the graph show up properly when used capacity > capacity when max capacity configured to be > capacity is not possible in a fashion that shows up both capacity and max capacity properly.  

Another issue with using the relative ones is if max capacity is < capacity:
root queue = 100%
root.test: cap = 20%, max capacity = 100%, absolute cap = 20%, absolute max = 100%
root.test.a1: cap = 80%, max capacity = 20%, absolute cap = 16%, absolute max = 20%

The above should be a valid config but the graph would totally be messed up if displaying capacity 80% and max capacity 20%.

I also changed used capacity to be what utilization was defined as. I think this will make more sense to the user and matches what was in 0.20.X/1.0.  I removed utilization and added an absolute used capacity that can be used by the bar graphs. 

While I was in there I also changed it so that instead of opening all the divs and then closing the leaf queue ones, now everything starts closed and we only open the parent queues.

> The capacity scheduler web ui has bar graphs showing the capacity/used capacity/max capacity for each queue. The used capacity it is showing is actually the % of its parents queue it is using, which doesn't make sense on the bar graphs when compared to the capacity and max capacity of that particular queue.  The bar graphs should be using utilization so that the user can see that its using x% or the y% allocated to that queue.
> I will attach some screen shots showing the issue.
