Rohith commented on YARN-3284:
------------------------------

Hi [~xgong], thanks for working on this Jira.
     For displaying application headroom for running applications( one of the point in YARN-3273),
it is required to expose applicationHeadroom field in the ApplicationAttemptMetrics.java.
Would you please mind adding this field in your patch that helps retrieve headroom?

> Current, we have some extra metrics about the application and current attempt in RM Web
UI. We should expose that information through YARN Command, too.
> 1. Preemption metrics
> 2. application outstanding resource requests
> 3. container locality info
