Subject [jira] [Commented] (AURORA-96) Implement fair share scheduling for non-production tasks
Date Mon, 05 Jan 2015 18:44:34 GMT

Bill Farner commented on AURORA-96:
-----------------------------------

Presumably you also want to the Preemptor to play a role in this to re-balance resources as
scheduling demands change.

You're correct about the determination of scheduling order.  There was at one point prioritization
in the scheduling queue, but we decided that this priority was illusory at best due to the
dynamic nature of scheduling work and available resources.

> Non-production tasks are allocated on a first-come first-served basis.  This means that
anybody could hold the entire cluster hostage (intentionally or otherwise).  The scheduler
should correct this by ensuring that non-production resources are distributed fairly.
