1.首先检查 zookeeper集群和kafka集群是否正常

发现没有问题

2.检查scala代码kafka配置文件是否写错

没有写错

3.检查kafka版本

原来是kafka版本错误

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.11${scala.version}</artifactId>
    <version>0.10.1.0</version>
</dependency>

替换

<dependency>

    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.11${scala.version}</artifactId>
    <version>0.10.0.0</version>
</dependency>
