             Summary: Scheduler::disconnected() should be called when the single master fails
                 Key: MESOS-2352
                 URL: https://issues.apache.org/jira/browse/MESOS-2352
             Project: Mesos
          Issue Type: Bug
          Components: master
            Reporter: Alexander Rukletsov
            Priority: Minor


According to the comments in "scheduler.hpp", "sched.cpp" and also common sense, the {{Scheduler::disconnected()}} callback should be also invoked when master fails. However, in case of {{StandaloneMasterDetector}} this won't happen, since it doesn't track master failures. Though the {{StandaloneMasterDetector}} is not intended for production use, we should update it so that framework authors observe consistent behaviour and can test their frameworks in a single-master setup.

As a short-term fix we may want to update comments in "scheduler.hpp" and "sched.cpp" for clarity.
