1.数据处理 

扩展脚本 （年月日）

vim log-extend.sh

#! /bin/bash

#infile=/home/sogou.500w.utf8

infile=$1

#outfile=/home/sogou_log.txt

outfile=$2

awk -F ' ' '{print $0" "substr($1,0,4)" "substr($1,4,2)" "substr($1,6,2)" "substr($1,8,2)}' $infile > $outfile

[root@master ~]# bash log-extend.sh sogou.500w.utf8 sogou_log.txt

过滤脚本（过滤搜索为空）

Vim log-filter.sh

#!/bin/bash

#infile=/home/sogou_log.txt

infile=$1

#outfile=/home/sogou_log.txt.flt

outfile=$2

awk -F " " '{if($2 != "" && $3 != "" && $2 != " " && $3 != " ") print $0}' $infile > $outfile

[root@master ~]# bash log-filter.sh sogou_log.txt  sogou_log.txt.flt

       

              

1. 上传文件到hdfs

基于HIve构建日志数据的数据仓库

创建数据库

hive> create database sogou;

使用数据库

Hive> use sogou;

创建扩展 4 个字段（年、月、日、小时）数据的外部表：

hive> CREATE EXTERNAL TABLE sogou_data(

ts string,

uid string,

keyword string,

rank int,

sorder int,

url string,

year int,

month int,

day int,

hour int)

    > ROW FORMAT DELIMITED

    > FIELDS TERMINATED BY ' '

    > STORED AS TEXTFILE;

OK

Time taken: 0.412 seconds

 

 

Hive表加载数据

load data inpath '/home/sogou_log.txt.flt' into table sogou_data;

 

 

 

创建带分区的表：

hive> CREATE EXTERNAL TABLE sogou_partitioned_data(

ts string,

uid string,

keyword string，

rank int,

sorder int,

url string)

    > PARTITIONED BY(year int,month int,day int,hour int)

    > ROW FORMAT DELIMITED

    > FIELDS TERMINATED BY ' '

    > STORED AS TEXTFILE;

 

 

 

 

 

设置动态分区

hive> set hive.exec.dynamic.partition.mode=nonstrict;

hive> INSERT OVERWRITE TABLE sogou_partitioned_data partition(year,month,day,hour) SELECT * FROM sogou_data;

查询测试

Hive> select * from sogou_data limit 10;

hive> select * from sogou_data limit 10;

hive> select * from sogou_data where uid='6961d0c97fe93701fc9c0d861d096cd9';

(1)查询总条数

hive> select count(*) from sogou_partitioned_data;

OK

5000000

(2)非空查询条数

hive> select count(*) from sogou_partitioned_data where keyword is not null and keyword!='';

5000000

Time taken: 28.606 seconds, Fetched: 1 row(s)

(3)无重复总条数

hive> select count(*) from(select count(*) as no_repeat_count from sogou_partitioned_data group by ts,uid,keyword,url having no_repeat_count=1) a;

OK

4999272

Time taken: 101.228 seconds, Fetched: 1 row(s)

(4)独立UID总数

hive> select count(distinct(uid)) from sogou_partitioned_data;

OK

1352664

Time taken: 44.639 seconds, Fetched: 1 row(s)

实现数据分析需求二：关键字分析

(1)查询频度排名（频度最高的前50词）

hive> select keyword,count(*)query_count from sogou_partitioned_data group by keyword order by query_count desc limit 50;

实现数据分析需求三：UID分析

(1)查询次数大于2次的用户总数

hive> select count(*) from(select count(*) as query_count  from sogou_partitioned_data group by uid having query_count > 2) a;

OK

546353

Time taken: 69.837 seconds, Fetched: 1 row(s)

(2)查询次数大于2次的用户占比

A:

hive> select count(*) from(select count(*) as query_count  from sogou_partitioned_data group by uid having query_count > 2) a;

OK

546353

Time taken: 69.837 seconds, Fetched: 1 row(s)

B：

hive> select count(distinct(uid)) from sogou_partitioned_data;

OK

1352664

A/B

hive> select 546353/1352664;

B:

hive> select count(*) from sogou_partitioned_data;

5000000

A/B

hive> select 4999869/5000000;

OK

0.9999738

(4) 直接输入URL查询的比例

A:

hive> select count(*) from sogou_partitioned_data where keyword like '%www%';

OK

73979

B:

hive> select count(*) from sogou_partitioned_data;

OK

5000000

A/B

hive> select 73979/5000000;

OK

0.0147958

实现数据分析需求四：独立用户行为分析

(1)查询搜索过”仙剑奇侠传“的uid，并且次数大于3

hive> select uid,count(*) as cnt from sogou_partitioned_data where keyword='仙剑奇侠传' group by uid having cnt > 3;
