--------------------------------
Summary: Add minimum master capability for draining and
deactivation states
Key: MESOS-9817
URL: https://issues.apache.org/jira/browse/MESOS-9817
Project: Mesos
Issue Type: Task
Components: master
Reporter: Joseph Wu
Since we are adding new fields to the registry to represent agent
draining/deactivation, we cannot allow downgrades of masters while such
features are in use.
A new minimum capability should be added to the registry with the appropriate
documentation:
