>
> Currently, at a regular interval, the fair scheduler computes a fair memory
> share for each queue and application inside it. This fair share is not used
> for scheduling decisions, but is displayed in the web UI, exposed as a
> metric, and used for preemption decisions.
> With DRF and multi-resource scheduling, assigning a memory share as the fair
> share metric to every queue no longer makes sense. It's not obvious what the
> replacement should be, but probably something like fractional fairness within
> a queue, or distance from an ideal cluster state.
