Question

我开发了一个Java类，它从Kafka队列中读取数据并将其打印出来

ZkHosts zkHosts=new ZkHosts("localhost:2181");
String topic_name="test";
String consumer_group_id="storm";
String zookeeper_root="";
SpoutConfig kafkaConfig=new SpoutConfig(zkHosts, 
        topic_name, zookeeper_root, consumer_group_id);
kafkaConfig.scheme=new SchemeAsMultiScheme(new StringScheme());
/*kafkaConfig.forceFromStart=false;
kafkaConfig.startOffsetTime =-2;*/

KafkaSpout kafkaSpout = new KafkaSpout(kafkaConfig);
TopologyBuilder builder=new TopologyBuilder();
//builder.setSpout("KafkaSpout", kafkaSpout, 1);
builder.setSpout("KafkaSpout", kafkaSpout);
builder.setBolt("PrinterBolt", new PrinterBolt()).globalGrouping("KafkaSpout");
Map<String, Object> conf = new HashMap<String, Object>();
conf.put(Config.TRANSACTIONAL_ZOOKEEPER_PORT, 2181);
conf.put(Config.TRANSACTIONAL_ZOOKEEPER_SERVERS, Arrays.asList("localhost"));
conf.put(Config.STORM_ZOOKEEPER_SESSION_TIMEOUT, 20000);
conf.put(Config.STORM_ZOOKEEPER_CONNECTION_TIMEOUT, 20000);
conf.put(Config.STORM_ZOOKEEPER_RETRY_TIMES, 3);
conf.put(Config.STORM_ZOOKEEPER_RETRY_INTERVAL, 30);
LocalCluster cluster=new LocalCluster();
try{
    cluster.submitTopology("KafkaConsumerTopology", conf, builder.createTopology());
    Thread.sleep(120000);
}catch (Exception e) {
    //throw new IllegalStateException("Couldn't initialize the topology", e);
    System.out.println(e.getMessage());
}

编码后，我正在将Maven构建为JAR文件并将jar移至Amazon AWS集群
然后运行nohup java -cp uber-***-0.0.1-SNAPSHOT.jar com.***.&&&.kafka.App

但我在这里遇到错误，有人能告诉我在部署中我做了什么错误吗？我在想我必须做的事情：

我需要在strom config文件夹中部署这个jar文件，我需要吗？但我确实将jar放在AWS（不在风暴文件夹中）的单独文件夹中
如何查看系统输出
我是否需要在项目中包含任何yml文件？

请查看以下异常：

@Matthias J. Sax和大家，感谢您的帮助。我在这里犯的错误是，我所遵循的部署过程是错误的。要部署toplogy构建，我必须遵循以下流程，

Jar必须进入风暴AWS文件夹，然后必须在命令下运行以使其被Storm识别

rm -f * .out

（nohup bin / storm nimbus＆gt; nimubus.out）＆amp;

（nohup bin / storm supervisor＆gt; supervisor.out）＆amp;

（nohup bin / storm jar topos / IoT.jar com.bridgera.iot.test.App01＆gt; IoT.out）＆amp;

在这里，我告诉风暴，它可以找到我的jar和主要类，从哪里可以找到拓扑构建器......

谢谢你们......
