Could not instantiate the executor. Make sure a planner module is on the classpath

运行Flink项目报错：Could not instantiate the executor. Make sure a planner module is on the classpath

原因：提示没有planner组件，需要加入planner这个依赖

pom.xml添加代码

    <dependency>
        <groupId>org.apache.flink</groupId>
        <artifactId>flink-table-planner_2.11</artifactId>
        <version>${flink.version}</version>
    </dependency>
