Michael Gummelt updated MESOS-6113:
-----------------------------------
Description:
*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.
