             Summary: Validate that schedulers cannot perform operations on offers with different allocation roles.
                 Key: MESOS-6637
                 URL: https://issues.apache.org/jira/browse/MESOS-6637
             Project: Mesos
          Issue Type: Task
          Components: master
            Reporter: Benjamin Mahler


With support for multi-role frameworks, offers contain allocation info (currently just the role that the offer is being made to).

In theory, schedulers could perform offer operations across multiple roles, so long as the tasks, executors, and reservations individually don't mix roles. However, there doesn't seem to be a clear reason to allow this. So, we will validate against combining offers from multiple roles. This also makes it semantically consistent with single-role frameworks (since they do not do this either).
