--------------------------------------
Summary: Allow schedulers to decide whether to consume resources
as revocable or non-revocable.
Key: MESOS-5525
URL: https://issues.apache.org/jira/browse/MESOS-5525
Project: Mesos
Issue Type: Epic
Components: framework api, allocation
Reporter: Benjamin Mahler
The idea here is that although some resources may only be consumed in a
revocable manner (e.g. oversubscribed resources, resources from "spot
instances", etc), other resources may be consumed in a non-revocable manner
(e.g. dedicated instance, on-premise machine).
However, a scheduler may wish to consume these non-revocable resources in a
revocable manner. For example, if the scheduler has quota for non-revocable
resources it may want not want to use its quota for a particular task and may
wish to launch it in a revocable manner out of its fair share. See:
In order to support this, we should adjust the meaning of revocable and
non-revocable resources in order to allow schedulers to decide how to consume
them. The scheduler could choose to consume non-revocable resources in a
revocable manner in order to use its fair share of revocable resources rather
than its quota.
