* Why are we doing this manipulation here and not in the Java code?
* backticks are antiquated in modern bash. Use {{$()}} construction
* What happens if tput gives you zero or an error because you are on a
non-addressable terminal? (You can generally simulate this by unset TERM or
equivalent env var)
> Add a 'yarn top' tool to help understand cluster usage

> 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.
