init_book_result.sql

-- 设置sql_mode
set sql_mode = 'NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES';

-- 创建数据库result,并进行切换
create database book_result;

use book_result;

-- 创建图书类别浏览量表
CREATE TABLE t_books_type_borrow_count(
    type_name        varchar(100) not null,
    borrow_count        int not null
)DEFAULT CHARSET='utf8';

2.通过sqoop将mysql中的业务数据导入到大数据平台（hive）

在hive中建立映射的数据库

init_hive.sql

create database library;
use library;

-- 创建用户信息表

create table t_user_info (
    user_id STRING    comment "用户id",   
    user_name STRING  comment "用户姓名", 
    sex STRING        comment "用户姓名",       
    age INT           comment "用户性别"
) 
comment "用户信息表"
row format delimited fields terminated by ','
stored as textfile;

-- 创建图书表

create table t_book_info (
    book_id STRING    comment "图书id",   
    book_name STRING  comment "书名", 
    type_id STRING    comment "类别id"
) 
comment "图书表"
row format delimited fields terminated by ','
stored as textfile;

-- 创建图书类别表

create table dim_books_type (
    type_id STRING    comment "类别id",   
    type_name STRING  comment "类别名"
) 
comment "图书类别表"
row format delimited fields terminated by ','
stored as textfile;

-- 创建借书表

create table t_borrow_order (
    user_id STRING     comment "用户id",    
    book_id STRING     comment "图书id",    
    create_time STRING comment "创建时间"
) 
comment "借书表"
row format delimited fields terminated by ','
stored as textfile;

source /opt/sql/library/init_hive.sql;

导入mysql数据到hive中

此次mysql与hive中的表名都相同

sqoop import \

                            **     虚拟机**      端口号 mysql中的数据库名

--connect jdbc:mysql://bigdata004:3306/mall \

--username root \

--password root123 \

       mysql中的表名

--table t_user_info \

--num-mappers 1 \

--hive-import \

--fields-terminated-by "," \

--hive-overwrite \

导入dim_books_type

sqoop import \
--connect jdbc:mysql://bigdata004:3306/library \
--username root \
--password root123 \
--table dim_books_type \
--num-mappers 1 \
--hive-import \
--fields-terminated-by "," \
--hive-overwrite \
--hive-table library.dim_books_type

3.通过hive进行数据计算和数据分析 形成数据报表

--切换数据库
use library;
 
 
--创建图书类别借阅表
--从借书表中获取图书id 
--从图书表中获取图书id的类别id
--从类别表中获取类别名
--表中显示 类名 和 该类名的总数（）

 
create table if not exists library.dws_borrow_books_type_count
as
    select t3.type_name,count(t2.type_id) as borrow_count from (select book_id from t_borrow_order) t1
    inner join t_book_info t2 on t1.book_id=t2.book_id
    inner join dim_books_type t3 on t2.type_id=t3.type_id
    group by t3.type_name;

4.再通过sqoop将数据报表导出到mysql

-- sqoop导出数据到mysql

sqoop export \

                               主机名                 数据库

--connect jdbc:mysql://bigdata004:3306/result
--username root
--password root123 \

                mysql上的表名

--table t_city_sale_total
--num-mappers 1 \

                hdfs上的数据库位置

--export-dir /user/hive/warehouse/mall_bigdata.db/dws_sale_order_city_total
--input-fields-terminated-by "\001"

-- sqoop导出数据到mysql

sqoop export \
--connect jdbc:mysql://bigdata004:3306/book_result \
--username root \
--password root123 \
--table t_books_type_borrow_count \
--num-mappers 1 \
--export-dir /user/hive/warehouse/library.db/dws_borrow_books_type_count \
--input-fields-terminated-by "\001"

5.使用FineReport制作数据报表
