今天做的是MongDB日志分析，今天成功将数据导入到hive并进行一系列的数据清洗，并导入到mysql，最终未完成可视化操作，计划明天完成，下面是要求部分：
Result文件数据说明：
Ip：106.39.41.166,（城市）
Date：10/Nov/2016:00:01:02 +0800,（日期）
Day：10,（天数）
Traffic: 54 ,（流量）
Type: video,（类型：视频video或文章article）
Id: 8701（视频或者文章的id）
测试要求：
1、 数据清洗：按照进行数据清洗，并将清洗后的数据导入MongDB数据库中。
两阶段数据清洗：
（1）第一阶段：把需要的信息从原始日志中提取出来
ip: 199.30.25.88
time: 10/Nov/2016:00:01:03 +0800
traffic: 62
文章： article/11325
视频： video/3235
（2）第二阶段：根据提取出来的信息做精细化操作
ip--->城市 city（IP）
date--> time:2016-11-10 00:01:03
day: 10
traffic:62
type:article/video
id:11325
（3）MongDB数据库表结构:
create table data( ip string, time string , day string, traffic bigint,
type string, id string )
2、数据处理：
每天·统计最受欢迎的视频/文章的Top10访问次数 （video/article）
·按照地市统计最受欢迎的Top10课程 （ip）
·按照流量统计最受欢迎的Top10课程 （traffic）
3、数据可视化：将统计结果倒入MySql数据库中，通过图形化展示的方式展现出来。
下面是操作流程和步骤：
创建result表
create table result (ip String,data String,day String,traffic String,type String,id String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
导入数据
load data local inpath '/opt/software/result.txt' into table result;
创建result1表用于初步筛选
create table result1(ip String,data String,traffic String,type String,id String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
把type="video"的数据导入result1
insert into table result1(ip,data,traffic,type,id) (select ip,data,traffic,type,id from result where type="video");
创建result2
create table result2(ip String,data String,traffic String,type String,id String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
把type="article"的数据导入表
insert into table result2(ip,data,traffic,type,id) (select ip,data,traffic,type,id from result where type="article");
清洗result1
insert overwrite table result1 select ip as ip,sumbstring(data,8,length(data)-7) as data,traffic as traffic,type as type,id as id from result1;
清洗result2
insert overwrite table result2 select ip as ip,substring(data,8,length(data)-7) as data,traffic as traffic,type as type,id as id from result2;
创建result3表用于进一步清洗
create table result3 (ip String,data String,day String,traffic String,type String,id String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
把result中数据导入result3
insert into table result3(ip,data,day,traffic,type,id) (select ip,data,day,traffic,type,id from result where type="article"or type="video");
清洗data数据
insert overwrite table result3 select ip as ip,concat("2016-11-10 ",substring(data,11,length(data)-10)) as data,day as day,traffic as traffic,type as type,id as id from result3;
创建result4表用于数据清洗
create table result4 (ip String,data String,day String,traffic String,type String,id String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
导入数据
insert into table result4(ip,data,day,traffic,type,id) (select ip,data,day,traffic,type,id from result3);
select id,count(id)from result3 group by id order by count(id) desc limit 10;
截图：
select ip,count(ip)from result3 group by ip order by count(ip) desc limit 10;
导入到mysql
