I also opened https://issues.apache.org/jira/browse/MESOS-4144 to add the ability to add roles dynamically based on an API request to properly authorized principals. Thanks!

Please file a JIRA ticket and I'll sync with Neil regarding what the behavior should be with dynamic/implicit roles in mind. Thanks! MPark.

If the role specified in the reserve/unreserve operation doesn't exist in --roles on the master, it should reject the reservation on the /reserve endpoint. Why allow the reservation of roles if you can't use them if they are specified 2. If the role doesn't exist in --roles, and a reservation comes through, it should be added dynamically. This seems to make more sense to me. I.e. adding roles doesn't require a master restart. There is currently work in progress to add support for implicit roles (roles not specified via --roles). But, I agree that until we add that feature the /reserve endpoint should reject reservations for unknown roles. Not sure what the rationale was to allow this. @mpark?
