Create topic in multiple zookeepers with Kafka AdminUtils.CreateTopic JAVA API in Kafka 0.9.0.1 gives Error

Question

I am using below code snippet to create topic in multiple zookeepers with Kafka Java APIS. when I specify 2 zookeeprs IPs in zookeeperConnect variable it only creates topic in anyone of zookeeper. Both the zookeeper are 2 different kafka cluster. Any Help ?

   String zookeeperConnect = zookeeperIPs; // Multiple zookeeper IPs
   int sessionTimeoutMs = 10 * 1000;
   int connectionTimeoutMs = 8 * 1000;

   try {
    ZkClient zkClient = new ZkClient(
                zookeeperConnect,
                sessionTimeoutMs,
                connectionTimeoutMs,
                ZKStringSerializer$.MODULE$);

    boolean isSecureKafkaCluster = false;
    ZkUtils zkUtils = new ZkUtils(zkClient, 
    new ZkConnection(zookeeperConnect), isSecureKafkaCluster);

        String topic1 = "nameofTopictobeCreated";
        int partitions = 1;
        int replication = 1;
        Properties topicConfig = new Properties(); // add per-topic configurations settings here

        AdminUtils.createTopic(zkUtils, topic1, partitions, replication, topicConfig);

工具AdminUtils假定all指定ZK属于同一个集群，因此与其中一个集合通信就足够了（因为ZK节点将自动同步）。

如果要在两个群集中创建主题，则需要两次发出命令，每次使用不同的ZK节点。
