Subject [jira] [Updated] (MESOS-6113) Offer reserved resources as revocable
Date Wed, 31 Aug 2016 18:52:20 GMT

     [ https://issues.apache.org/jira/browse/MESOS-6113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
