Neil Conway updated MESOS-7636:
-------------------------------
Issue Type: Improvement (was: Bug)
> Add DomainInfo to Resource
> --------------------------
>
> Key: MESOS-7636
> URL: https://issues.apache.org/jira/browse/MESOS-7636
> Project: Mesos
> Issue Type: Improvement
> Reporter: Neil Conway
> Assignee: Neil Conway
> Labels: mesosphere
>
> Add a new {{domain}} field to {{Resource}}, which identifies the domain where
> the resources are located.
> It would be nice to add this to a higher-level message, like {{Offer}}, but
> we need to account for the possibility that different resources in a single
> offer come from different domains -- e.g., when support for external resource
> providers is introduced.
> It will now be possible for an agent's checkpointed resources to change when
> the agent is drained and restarted. Combined with the change to preserve
> AgentID across agent drains (MESOS-6223), this will mean that if an agent
> re-registers, its resources might have changed; previous copies of the
> resource in the master's in-memory state will need to be updated.
> This also means that if a framework has cached the properties of a persistent
> volume it created, subsequently attempting to destroy that volume with the
> old persistent volume JSON may not succeed, because the PV's properties have
> changed.
