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

I agree. Even for mappers and reducers container resource asks may vary, and the memory and the cores contain more information than the number of containers.

> 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.
