             Summary: Disable strict registry
                 Key: MESOS-5833
                 URL: https://issues.apache.org/jira/browse/MESOS-5833
             Project: Mesos
          Issue Type: Improvement
          Components: master
            Reporter: Neil Conway
            Assignee: Neil Conway
            Priority: Blocker


I'd like to propose that we disable the {{--registry_strict}} master flag for Mesos 1.0.0.

Rationale:

* This feature has always been marked as experimental and sparsely documented.
* The strict registry will no longer be relevant once support for partition-aware frameworks is introduced (MESOS-4049).
* If we can assume that no frameworks are assuming the strict-registry behavior, we can simplify the design/implementation of MESOS-4049. It also makes the system's current behavior easier to explain, and makes the current LOST behavior more similar to the proposed UNREACHABLE behavior in MESOS-4049.

Note that if we disable the {{--registry_strict}} flag but keep the code (for now), we can always re-enable the feature if any users complain. However, a recent email to the {{user}} and {{dev}} lists did not result in anyone volunteering that they are using the strict registry.
