【慕课网实战】Spark Streaming实时流处理项目实战笔记二十一之铭文升级版

铭文一级：

DataV功能说明
1）点击量分省排名/运营商访问占比
Spark SQL项目实战课程： 通过IP就能解析到省份、城市、运营商

2）浏览器访问占比/操作系统占比
Hadoop项目：userAgent

DataV访问的数据库(MySQL),需要能够在公网上访问

DataV测试数据
CREATE TABLE course_click_count
(

day VARCHAR(10),
course_id VARCHAR(10),
click_count long
);

INSERT INTO course_click_count values (1,'20171111','112',8000);

有兴趣的小伙伴，可以把如上的静态数据准备成sql语句，插入到MySQL中去，
然后在DataV组件上通过sql的方式展示出来。

铭文二级（自己看官网吧）：

DataV的使用、主要是数据库的连接，操作是写sql语句，个人版只有mysql数据库

无法使用HBase，所以需要自己写到mysql里面去
