> Before the recent refactor The nodes had information in them about how much
> resources they were using. This information is not hidden inside
> SchedulerNode. Similarly resource usage information about an application, or
> in aggregate is only available through the Scheduler and there is not
> interface to pull it out.
> We need to expose APIs to get Resource and Container information from the
> scheduler, in aggregate across the entire cluster, per application, per node,
> and ideally also per queue if applicable (although there are no JIRAs I am
> aware of that need this right now).
