Subject [jira] [Commented] (MESOS-6113) Offer reserved resources as revocable
Date Thu, 01 Sep 2016 17:39:20 GMT


Michael Gummelt commented on MESOS-6113:

I tend to think of quota as just another interface to marking resources as reserved, but I
understand there are some differences, yes.

>                 Key: MESOS-6113
>                 URL:
>             Project: Mesos
>          Issue Type: Task
>          Components: allocation
>    Affects Versions: 1.0.1
>            Reporter: Michael Gummelt
> *Goal:*
> I have high-priority Spark jobs, and best-effort jobs.  I need my high-priority jobs
to pre-empt my best-effort jobs, so I'd like to launch the best-effort jobs on revocable resources.

> *Problem:*
> Revocable resources are currently only created via oversubscription, where resources
allocated to but not used by a framework will be offered to other frameworks.  This doesn't
support the ability for a high-pri framework to start up and pre-empty a low-pri framework.
> *Solution:*
> Let's allow quota (and ideally any reserved resources) to be configurable to be offered
as revocable resources to other frameworks that don't register with the role.
