Subject: [jira] [Updated] (MAPREDUCE-3625) CapacityScheduler web-ui display

Jason Lowe updated MAPREDUCE-3625:
----------------------------------

    Attachment: MAPREDUCE-3625.patch

Patch reworks capacity scheduler UI to fix the reported problem and make the UI a bit easier to read in general.

Green now represents used capacity instead of spare capacity and always grows from left to right.  The color of the bar changes to orange if the used capacity goes over 100%, and it doesn't streak off the right end of the page as it did previously.

Also added a legend so it's clear what the colors indicate and added a used capacity column for quick reference.

> The display of the queue's used capacity at runtime is broken because it display's 'used' relative to the queue's capacity and not the parent's capacity as shown in the above attachment.
> The display should be relative to parent's capacity and not leaf queues as everything else in the display is relative to parent's capacity.
