Java Kafka使用TopicCommand创建主题_Java_Apache Kafka - Fatal编程技术网

Java Kafka使用TopicCommand创建主题

Java Kafka使用TopicCommand创建主题,java,apache-kafka,Java,Apache Kafka,我想用java创建一个主题。这是我的密码 String s = "--topic pt8 --create --zookeeper 10.11.6.52:2181 --replica-assignment 7"; String[] args2 = s.split(" "); TopicCommand.main(args2); 但有一个错误: [ZkClient-EventThread-14-10.11.6.52:2181]INFO o.I.z.ZkEventThread-启动ZkClient事

我想用java创建一个主题。这是我的密码

String s = "--topic pt8 --create --zookeeper 10.11.6.52:2181 --replica-assignment 7";
String[] args2 = s.split(" ");
TopicCommand.main(args2);
但有一个错误:

[ZkClient-EventThread-14-10.11.6.52:2181]INFO o.I.z.ZkEventThread-启动ZkClient事件线程

[main]INFO o.I.z.ZkClient-正在等待状态同步连接 [main EventThread]信息o.I.z.ZkClient-zookeeper状态已更改 (同步连接)

执行主题命令时出错: java.lang.ExceptionInInitializeError

[ZkClient-EventThread-14-10.11.6.52:2181]INFO o.I.z.ZkEventThread- 终止ZkClient事件线程

--列表--zookeeper 10.11.6.52:2181
可以得到结果。
--delete--zookeeper 10.11.6.52:2181--topic pt7
执行topic命令时出错:null

My pom.xml:

        <dependency>
        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka_2.11</artifactId>
        <version>0.10.2.1</version>
    </dependency>

        <groupId>org.apache.kafka</groupId>
        <artifactId>kafka-clients</artifactId>
        <version>0.10.2.1</version>
    </dependency>
错误:

线程“main”kafka.admin.AdminOperationException中的异常:java.lang.ExceptionInInitializeError


不要使用shell命令并试图从JAVA执行它,而是使用KAFKA管理客户端API,它应该与KAFKA 0.11+一起使用

以下是一段代码片段:

void setUpKafkaTopics(KafkaAdminClient kafkaAdminClient) throws ExecutionException, InterruptedException {
  final Map<String, Integer> topics = new HashMap<>();
  topics.put(topicName, numOfPartitions);
  kafkaAdminClient.createTopics(topics, getTopicConfig(), replicationFactor);
}


Map<String, String> getTopicConfig() {
  Map<String, String> topicConfiguration = new HashMap<>();
  topicConfiguration.put(TopicConfig.UNCLEAN_LEADER_ELECTION_ENABLE_CONFIG,
     Boolean.FALSE.toString());
  topicConfiguration.put(TopicConfig.CLEANUP_POLICY_CONFIG,
     TopicConfig.CLEANUP_POLICY_DELETE);
  topicConfiguration.put(TopicConfig.COMPRESSION_TYPE_CONFIG,
     KAFKA_TOPIC_COMPRESSION_TYPE);
  topicConfiguration.put(TopicConfig.MIN_IN_SYNC_REPLICAS_CONFIG,
     KAFKA_TOPIC_MIN_IN_SYNC_REPLICAS.toString()); 
  topicConfiguration.put(TopicConfig.RETENTION_MS_CONFIG,
     KAFKA_TOPIC_RETENTION_MS.toString()); 
  return topicConfiguration;
}
void setUpKafkaTopics(KafkaAdminClient KafkaAdminClient)引发ExecutionException、InterruptedException{
最终映射主题=新HashMap();
topics.put(topicName,numOfPartitions);
kafkaAdminClient.createTopics(topics,getTopicConfig(),replicationFactor);
}
映射getTopicConfig(){
Map topicConfiguration=new HashMap();
topicConfiguration.put(TopicConfig.UNCLEAN_LEADER_ELECTION_ENABLE_CONFIG,
Boolean.FALSE.toString());
topicConfiguration.put(TopicConfig.CLEANUP\u POLICY\u CONFIG,
TopicConfig.CLEANUP\u POLICY\u DELETE);
topicConfiguration.put(TopicConfig.COMPRESSION\u TYPE\u CONFIG,
卡夫卡(主题压缩型);
topicConfiguration.put(TopicConfig.MIN)在同步副本配置中,
KAFKA_TOPIC_MIN_IN_SYNC_replications.toString());
topicConfiguration.put(TopicConfig.RETENTION\u MS\u CONFIG,
卡夫卡的主题是保留;
返回主题配置;
}

Zookeeper正在运行吗?我正在使用群集Zookeeper IP<代码>--列表--zookeeper 10.11.6.52:2181运行良好。我认为
0.10.2.1
依赖项不可用。是的,很抱歉,我刚才看到你在使用
0.10.2.1
,管理员客户端出现
0.11.x
注意:这不是“我的”问题
void setUpKafkaTopics(KafkaAdminClient kafkaAdminClient) throws ExecutionException, InterruptedException {
  final Map<String, Integer> topics = new HashMap<>();
  topics.put(topicName, numOfPartitions);
  kafkaAdminClient.createTopics(topics, getTopicConfig(), replicationFactor);
}


Map<String, String> getTopicConfig() {
  Map<String, String> topicConfiguration = new HashMap<>();
  topicConfiguration.put(TopicConfig.UNCLEAN_LEADER_ELECTION_ENABLE_CONFIG,
     Boolean.FALSE.toString());
  topicConfiguration.put(TopicConfig.CLEANUP_POLICY_CONFIG,
     TopicConfig.CLEANUP_POLICY_DELETE);
  topicConfiguration.put(TopicConfig.COMPRESSION_TYPE_CONFIG,
     KAFKA_TOPIC_COMPRESSION_TYPE);
