How to use

connectString

method

in

kafka.zk.EmbeddedZookeeper

public static void startServer() throws RuntimeException {
 if (serverStarted && serverClosed) {
  throw new RuntimeException("Kafka test server has already been closed. Cannot generate Kafka server twice.");
 }
 if (!serverStarted) {
  serverStarted = true;
  zkConnect = TestZKUtils.zookeeperConnect();
  zkServer = new EmbeddedZookeeper(zkConnect);
  zkClient = new ZkClient(zkServer.connectString(), 30000, 30000, ZKStringSerializer$.MODULE$);
  kafkaPort = TestUtils.choosePort();
  Properties props = TestUtils.createBrokerConfig(brokerId, kafkaPort, true);
  KafkaConfig config = new KafkaConfig(props);
  Time mock = new MockTime();
  kafkaServer = TestUtils.createServer(config, mock);
 }
}

ZkClient zkClient = new ZkClient(zkServer.connectString(), 30000, 30000, ZKStringSerializer$.MODULE$);
Properties props = TestUtils.createBrokerConfig(0, TestUtils.choosePort(), false);
KafkaConfig config = new KafkaConfig(props);
