“线程中的异常”；“主要”；java.lang.RuntimeException:在执行Storm时发现多个defaults.yaml资源

我正在尝试执行这里的教程

卡夫卡风暴拓扑代码为：

package com.storm;

import storm.kafka.KafkaSpout;
import storm.kafka.SpoutConfig;
import storm.kafka.StringScheme;
import storm.kafka.ZkHosts;
import backtype.storm.Config;
import backtype.storm.LocalCluster;
import backtype.storm.spout.SchemeAsMultiScheme;
import backtype.storm.topology.TopologyBuilder;

public class KafkaStormTopology {
public static void main(String[] args) {
  ZkHosts zk = new ZkHosts("10.25.3.208:2181");
  SpoutConfig config = new SpoutConfig(zk,"deepthy","",
"KafkaStorm");

 config.scheme = new SchemeAsMultiScheme(new StringScheme());

  config.forceFromStart = true;

  TopologyBuilder builder = new TopologyBuilder();
  builder.setSpout("KafkaSpout", new KafkaSpout(config), 1);
  builder.setBolt("Bolt", new FileBolt(), 1).globalGrouping("KafkaSpout");

  LocalCluster cluster = new LocalCluster();

  Config conf = new Config();
  conf.setDebug(true);
  cluster.submitTopology("SampleTopology", conf, builder.createTopology());
 }
}

我尝试在pom.xml中将范围从“compile”更改为“provided”，但得到了相同的错误

关于如何解决此问题的任何建议。

您的jar包含文件

defaults.yaml

，其中不允许使用该文件。您需要从jar组装步骤中排除该文件。我建议使用

maven-jar-plugin

而不是

maven-assembly-plugin

，并“手动”包含所有需要的文件——这也有助于“最小化”您的jar，使其只包含您需要的内容：

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>

        <executions>
                <execution>
                    <id>YOUR-ID</id>
                    <phase>package</phase>
                    <goals>
                        <goal>jar</goal>
                    </goals>
                    <configuration>
                        <finalName>JAR-FILE-NAME-PREFIX</finalName>
                        <classifier>JAR-FILE-NAME-SUFFIX</classifier>

                        <archive>
                            <manifestEntries>
                                <mainClass>com.storm.KafkaStormTopology</mainClass>
                            </manifestEntries>
                        </archive>

                        <includes>
                            <include>packages/to/include/**/*.java</include>
                            <!-- more include here -->
                        <includes>
                    </configuration>
                </execution>
        </executions>

您正在运行什么命令来上传jar？
