题目要求：
具体操作：
①hive路径下建表：sale
create table sale
(day_id String, sale_nbr String, buy_nbr String, cnt String, round String)
ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
②导入数据：
load data local inpath '/opt/module/data/sales.csv' into table sale;
③数据清洗：
3、数据分析处理：
（1）统计每天各个机场的销售数量和销售金额。要求的输出字段 day_id,sale_nbr,,cnt,round 日期编号，卖出方代码，数量，金额。
命令：
查询语句：
select day_id,sale_nbr,sum(cnt),sum(round) from sale where sale_nbr like 'C%' group by day_id,sale_nbr;
创建表table1：
create table table1(day_id String,sale_nbr String, cnt String,round String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
将查询语句保存至table1：
insert overwrite table table1 select day_id,sale_nbr,sum(cnt),sum(round) from sale where sale_nbr like 'C%' group by day_id,sale_nbr;
（2）统计每天各个代理商的销售数量和销售金额.要求的输出字段 day_id,sale_nbr,cnt,round 日期编号，卖出方代码，数量，金额
命令：
查询语句：
select day_id,sale_nbr,sum(cnt),sum(round) from sale where sale_nbr like 'O%' or buy_nbr like 'O%' group by day_id,sale_nbr;
创建表table2：
create table table2(day_id String,sale_nbr String, cnt String,round String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
将查询结果保存至table2：
insert overwrite table table2 select day_id,sale_nbr,sum(cnt),sum(round) from sale where sale_nbr like 'O%' or buy_nbr like 'O%' group by day_id,sale_nbr;
（3）统计每天各个代理商的销售活跃度。 要求的输出字段 day_id,sale_nbr, sale_number 日期编号，卖出方代码，交易次数（买入或者卖出均算交易次数）
命令：
查询语句：
select day_id,sale_nbr,count(sale_nbr)from sale where sale_nbr like "O%" group by sale_nbr,day_id;
创建表table3：
create table table3(day_id String,sale_nbr String, sale_number String) ROW format delimited fields terminated by ',' STORED AS TEXTFILE;
将查询结果保存至表table3：
insert overwrite table table3 select day_id,sale_nbr,count(sale_nbr)from sale where sale_nbr like "O%" group by sale_nbr,day_id;
导入mysql：
一
1.建表（可视化建表）：
2.sqoop路径下执行命令：
bin/sqoop export
> --connect jdbc:mysql://master:3306/mysql
> --username root
> --password 000000
> --table table1
> --num-mappers 1
> --export-dir /user/hive/warehouse/table1
> --input-fields-terminated-by ","
二
bin/sqoop export
> --connect jdbc:mysql://master:3306/mysql
> --username root
> --password 000000
> --table table2
> --num-mappers 1
> --export-dir /user/hive/warehouse/table2
> --input-fields-terminated-by ","
三
bin/sqoop export
> --connect jdbc:mysql://master:3306/mysql
> --username root
> --password 000000
> --table table3
> --num-mappers 1
> --export-dir /user/hive/warehouse/table3
> --input-fields-terminated-by ","
