----------------------------------
Summary: Add DomainInfo to Resource
Key: MESOS-7636
URL: https://issues.apache.org/jira/browse/MESOS-7636
Project: Mesos
Issue Type: Bug
Reporter: Neil Conway
Assignee: Neil Conway
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.
