Vinod Kumar Vavilapalli commented on YARN-451:
----------------------------------------------
Agreed about having it on the listing page, but that page is already dense.
Have to do some basic UI design.
Again, like I mentioned, Hadoop-1 was different as number of maps, reduces
doesn't change after job starts. Whereas in Hadoop-2, memory/cores allocated
slowly increases over time , so it may or may not be of much use. I am
ambivalent about adding it.

> Key: YARN-451
> URL: https://issues.apache.org/jira/browse/YARN-451
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.0.3-alpha
> Reporter: Lohit Vijayarenu
> Priority: Minor
>
> 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.
