>
> The UI for capacity scheduler displays 'pending tasks' counts. However the
> capacity scheduler does not update these counts to be the actual values for
> optimization purposes, for e.g. to avoid walking all pending jobs on all
> heartbeats. Hence this information is not very accurate.
> Also, while 'running tasks' counts are useful to compare against capacities
> and limits, 'pending tasks' counts do not add too much user value. A better
> count to display would be the number of running and pending jobs.
