Varun Vasudev commented on YARN-4285:
-------------------------------------
Thanks for the explanation [~leftnoteasy]. So it looks like for internal
accounting purposes we should count reserved containers as used resources but
from a web UI perspective, we should subtract reserved resources and show them
seperately?
> Display resource usage as percentage of queue and cluster in the RM UI

> Currently, we display the memory and vcores allocated to an app in the RM UI.
> It would be useful to display the resources consumed as a %of the queue and
> the cluster to identify apps that are using a lot of resources.
