Benjamin Mahler created MESOS-832:
-------------------------------------

             Summary: Scheduler Driver should reject messages from a non-leading master.
                 Key: MESOS-832
                 URL: https://issues.apache.org/jira/browse/MESOS-832
             Project: Mesos
          Issue Type: Bug
            Reporter: Benjamin Mahler
            Priority: Blocker


This will act as a safeguard against a split-brain scenario, where a non-leading Master still believes it is the leader.

As an example, this can occur if the disk and network I/O stall on the leading Master. In this event, most components cannot make progress, as they perform logging. However, components that do not perform logging can continue to operate. Of particular interest is the SlaveObserver, which will continue to operate and inform the Master that all slaves are unhealthy due to the network being down on the Master.
