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.
