在Flink UI上传jar包时，如果用 createLocalEnvironmentWithWebUI 的方式则不能使用 flink run 的方式提交，只能使用Java -jar的方式

若要使用集群提交，需通过StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment() ，创建流式对象

        StreamExecutionEnvironment env =  StreamExecutionEnvironment.getExecutionEnvironment();
//      createLocalEnvironmentWithWebUI(new org.apache.flink.configuration.Configuration());
