             Summary: Handle a network partition between Master and Slave
                 Key: MESOS-1529
                 URL: https://issues.apache.org/jira/browse/MESOS-1529
             Project: Mesos
          Issue Type: Bug
            Reporter: Dominic Hamon


If a network partition occurs between a Master and Slave, the Master will remove the Slave (as it fails health check) and mark the tasks being run there as LOST. However, the Slave is not aware that it has been removed so the tasks will continue to run.

There are at least two possible approaches to solving this issue:

1. Introduce a health check from Slave to Master so they have a consistent view of a network partition. We may still see this issue should a one-way connection error occur.

2. Be less aggressive about marking tasks and Slaves as lost. Wait until the Slave reappears and reconcile then. We'd still need to mark Slaves and tasks as potentially lost (zombie state) but maybe the Scheduler can make a more intelligent decision.
