Sangjin Lee commented on YARN-451:
----------------------------------

I am going to upload a single patch to get your feedback. I wanted to get your feedback first
to validate the approach before I break out sub-tasks and post separate patches. This single
patch is solely for review, and is not to be merged.

> 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.
