运行Flink程序报错：原因是因为在pom.xml中导入了client依赖。

<dependency><groupId>org.apache.flink</groupId><artifactId>flink-scala_2.11</artifactId><version>1.7.2</version>
</dependency>
<!--.apache.flink/flink-streaming-scala-->
<dependency><groupId>org.apache.flink</groupId><artifactId>flink-streaming-scala_2.11</artifactId><version>1.7.2</version>
</dependency><dependency><groupId>org.apache.flink</groupId><artifactId>flink-clients_2.11</artifactId><version>1.6.1</version>
</dependency>

去除掉以下依赖即可：

<dependency><groupId>org.apache.flink</groupId><artifactId>flink-clients_2.11</artifactId><version>1.6.1</version>
</dependency>
