---------------------------------------
[~bmahler] [~neilc] Do we plan to work on it for the 1.4.0 release? If not,
please retarget it for 1.5.0.
> Ensure hierarchical roles work with old Mesos agents

> Project: Mesos
> Issue Type: Bug
> Reporter: Neil Conway
> Assignee: Neil Conway
> Labels: mesosphere
>
> If the Mesos master supports hierarchical roles but the agent does not, we
> need to ensure that we avoid putting the agent into a bad state, e.g., if the
> user creates a persistent volume.
> One approach is to use an agent capability for hierarchical roles, and
> disallow creating persistent-volumes using a hierarchical role if the agent
> doesn't have the capability. We could also use an agent version check,
> although until MESOS-6975 is implemented, that will be a bit awkward.
