--------------------------------
Assignee: Greg Mann
> Master should clean up operations from downgraded agents
> --------------------------------------------------------
>
> Key: MESOS-9535
> URL: https://issues.apache.org/jira/browse/MESOS-9535
> Project: Mesos
> Issue Type: Task
> Reporter: Greg Mann
> Assignee: Greg Mann
> Priority: Major
> Labels: foundations, mesosphere
>
> If a Mesos agent is upgraded to provide reliable feedback for operations on
> agent default resources and then later downgraded, the master may possess
> in-memory state related to operations requesting feedback which should be
> cleaned up. We should update the master to detect downgraded agents and clean
> up appropriately.
> This ticket does not include sending best-effort feedback to schedulers for
> operations on downgraded agents.
> The upgrade documentation should also be updated with a note about the impact
> of downgrades on operation feedback.
