>             Project: Mesos
>          Issue Type: Task
>          Components: allocation, multitenancy
>    Affects Versions: 1.0.1

> *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.
