org.voltcore.messaging.HostMessenger
Host messenger contains all the code necessary to join a cluster mesh, and create mailboxes that are addressable from anywhere within that mesh. Host messenger also provides a ZooKeeper instance that is maintained within the mesh that can be used for distributed coordination and failure detection.

    public void testSPMasterChange() throws Exception
    {
        ZooKeeper zk = getClient(0);
        VoltZK.createPersistentZKNodes(zk);
        LeaderCache spwriter = new LeaderCache(zk, VoltZK.iv2masters);
        HostMessenger hm = mock(HostMessenger.class);
        when(hm.getZK()).thenReturn(m_messengers.get(0).getZK());
        Cartographer dut = new Cartographer(hm, 0, false);
        // Startup partitions
        spwriter.start(true);
        spwriter.put(0, 0l);
        verify(hm, timeout(10000)).send(anyLong(), any(VoltMessage.class));
