             Summary: Reconciliation for unreachable agent after master failover is incorrect
                 Key: MESOS-6445
                 URL: https://issues.apache.org/jira/browse/MESOS-6445
             Project: Mesos
          Issue Type: Bug
          Components: master
            Reporter: Neil Conway
            Assignee: Neil Conway

    If the master fails over and an agent does not re-register within the
    `agent_reregister_timeout`, the master marks the agent as unreachable in
    the registry and sends `slaveLost` for it. However, we neglected to
    update the master's in-memory state for the newly unreachable agent;
    this meant that task reconciliation would return incorrect results
    (until/unless the next master failover).
