Sangjin Lee commented on YARN-451:
----------------------------------
That is another approach. However, I think being able to sort by resource usage
is a crucial piece for this. When you have a large number of apps running,
being able to identify the top apps in terms of (aggregate) resource demand is
real useful, and sorting is the best way to get at it. If it were strings,
natural sorting may not work within the same apps as well as across apps.
Thoughts?

> ResourceManager webUI shows list of RUNNING applications, but it does not
> tell which applications are requesting more resource compared to others. With
> cluster running hundreds of applications at once it would be useful to have
> some kind of metric to show high-resource usage applications vs low-resource
> usage ones. At the minimum showing number of containers is good option.
