> It would be helpful to have a 'yarn top' tool that would allow administrators 
> to understand which apps are consuming resources.
> Ideally the tool would allow you to filter by queue, user, maybe labels, etc 
> and show you statistics on container allocation across the cluster to find 
> out which apps are consuming the most resources on the cluster.
