public class SocketSourceDemo {
    public static void main(String[] args) throws Exception {

        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

        env.setParallelism(1);

        DataStreamSource<String> socketTextStream = env.socketTextStream("127.0.0.1", 9987);
