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. -- This message is automatically generated by JIRA.
