------------------------------------------------------------
Does the section section in MESOS-4392 help? It is saying lend out the un-used
quota to other framework and reclaim them back when needed.
{code}
A greedy analytics batch system wants to use as much of the cluster as possible
to maximize computational throughput. When a competing web service with fixed
task size starts up, there must be sufficient resources to run it immediately.
The operator can reserve these resources by setting quota. However, if these
resources are kept idle until the service is in use, this is wasteful from the
analytics job's point of view. On the other hand, the analytics job should hand
back reserved resources to the service when needed to avoid starvation of the
latter.

> Key: MESOS-6113
> URL: https://issues.apache.org/jira/browse/MESOS-6113
> 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.
