    zkClient.create("/", null, CreateMode.PERSISTENT).get();


    // Start a new kafka server
    File logDir = TMP_FOLDER.newFolder();
    EmbeddedKafkaServer server = new EmbeddedKafkaServer(generateKafkaConfig(connectionStr, logDir));
    server.startAndWait();


    // Start a Kafka client
    KafkaClientService kafkaClient = new ZKKafkaClientService(zkClient);
    kafkaClient.startAndWait();

    Assert.assertEquals("Message 0", consumedMessages.poll(5, TimeUnit.SECONDS));


    // Now shutdown and restart the server on different port

    server = new EmbeddedKafkaServer(generateKafkaConfig(connectionStr, logDir));
    server.startAndWait();
