原因:有了

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-connector-kafka</artifactId>
    <version>${flink.version}</version>
</dependency>

这个依赖,还加了多余的kafkaclient依赖;去掉即可;下面这个不需要;

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>2.4.1</version>
</dependency>
