storm集成kafka报错org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for ...

写了一个storm集成kfaka的程序，kafkaSpout消费的数据作为storm的数据源。运行报错如下：

java.lang.RuntimeException: java.lang.RuntimeException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /brokers/topics/topic1/partitions

... 7 common frames omitted

原因：

有代码如下：

public static StormTopology buildTopo() {
    BrokerHosts brokerHosts = new ZkHosts("hdp01:2181");
    SpoutConfig spoutConfig = new SpoutConfig(brokerHosts, "topic1", "/kafka", "kafkaspout");
    spoutConfig.scheme = new SchemeAsMultiScheme(new MessageScheme());
    TopologyBuilder builder = new TopologyBuilder();
    builder.setSpout("spout", new KafkaSpout(spoutConfig));

在zookeeper的根目录下没有必要的节点/kafka

解决方法：

在zookeeper的根目录下创建节点/kafka
