这篇博客主要讨论了在运行Apache Flink程序时遇到的TableException，异常信息指出缺少ExecutorFactory来执行应用程序。解决方案是添加对应的flink-clients_2.12 jar包到项目依赖中，确保与Flink版本匹配，从而解决执行错误。

遇到上面这个报错提示是因为缺少flink client的jar,一般在项目中添加上相应版本的jar即可解决。

       <dependency>
            <groupId>org.apache.flink</groupId>
            <artifactId>flink-clients_2.12</artifactId>
            <!--替换成相应的flink版本-->
            <version>${flink.version}</version>
        </dependency>
