Sandy Ryza commented on YARN-786:
---------------------------------
The patch includes changes that make fetching these metrics much less
expensive, so I'm no longer worried about requiring users to explicitly ask for
it. Instead of copying all live containers from the scheduler and summing over
them to construct the ApplicationResourceUsageReport, we push this down into
the scheduler, which is already tracking the relevant numbers.

> it's a little more expensive to collect than the other fields in AppInfo.
