Qian Zhang commented on MESOS-3988:
-----------------------------------
[~neilc], we already have a ongoing project for dynamic role/weight:
https://issues.apache.org/jira/browse/MESOS-3177, does it meet your requirement?
> Implicit roles

> Key: MESOS-3988
> URL: https://issues.apache.org/jira/browse/MESOS-3988
> Project: Mesos
> Issue Type: Epic
> Reporter: Neil Conway
> Assignee: Neil Conway
> Labels: mesosphere, roles
>
> At present, Mesos uses a static list of roles that are configured when the
> master starts up. This places some severe limitations on how roles can be
> used (e.g., changing the set of roles requires restarting all the masters).
> As an alternative (or a precursor) to implementing full-blown dynamic roles,
> we could instead relax the concept of roles, so that:
> * frameworks can register with any role (subject to ACLs/authz)
> * reservations can be made for any role
> Open questions, at least to me:
> * This would mean weights cannot be configured dynamically. Is that okay?
> * Is this feature useful enough without dynamic ACL changes?
> * If we implement this (+ dynamic ACLs), do we also need dynamic roles?
