我在我的机器和我的其他机器上安装了Storm 1.1.1,我使用的是Kafka版本0.10.0.1.这两个服务都与Zookeeper 3.4.6版连接

我成功部署了我的拓扑,看起来像这样:

    public class SOTopology 
{
    public static void main (String[] args ) throws Exception
    {

        final String brokers = args[0];
        final String kafkaTopic = args[1];
        final String mongo_uri = args[2];
        final String mongo_collection = args[3];

        TopologyBuilder topology=new TopologyBuilder();
        topology.setSpout("KafkaSpout",new KafkaSpout<>(KafkaSpoutConfig.builder(brokers, kafkaTopic).build()), 1);
        topology.setBolt("FilterBolt", new Filterbolt(),1).shuffleGrouping("KafkaSpout");
        topology.setBolt("TagCountBolt", new TagCountBolt(),1).shuffleGrouping("FilterBolt");
        topology.setBolt("TopicBolt", new TopicBolt(),1).shuffleGrouping("FilterBolt");
        topology.setBolt("MongoDBBolt",new MongoDBBolt(),1).shuffleGrouping("TagCountBolt").shuffleGrouping("TopicBolt");

        Config conf = new Config();
        conf.setDebug(true);
        conf.put("mongo.uri", mongo_uri);
        conf.put("mongo.collection", mongo_collection);
        conf.setMaxSpoutPending(40);
        conf.setNumWorkers(10);
        conf.setDebug(true);

        StormSubmitter.submitTopology("StackOverflowTopology", conf, topology.createTopology());
    }
}

当我去我的StormUI时,我收到以下消息:Offset lags for kafka not …
