一、概述
入仓时机：业务数据、日志数据都同步到HDFS后。即Sqoop同步业务全量表完成后。
业务数据进入HDFS时机：全量数据每天凌晨将昨天的数据同步到HDFS昨天目录。增量数据实时同步到HDFS到binlog对应的日期目录。
日志数据进入HDFS时机：实时同步到日志行为发生的日期，JSON串中的ts字段解析出来的日期。
二、数据装载（HDFS -> Hive）
2.1 创建Hive表
共28张表：16张业务全量表、11张业务增量表、1张流量增量表。
注意1：Hive表默认是TextFile格式。
注意2：省份表和地区表为非分区表。

2.2 数据装载
省份表和城市表只需首次导入一次，其他业务表需要每天都装载。
2.2.1 初始化装载省份和地区表
[hadoop@hadoop102 ~]$ hive -e "load data inpath '/warehouse/db/gmall/base_province_full/2023-12-02' OVERWRITE into table dw_ods.ods_base_province;"
[hadoop@hadoop102 ~]$ hive -e "load data inpath '/warehouse/db/gmall/base_region_full/2023-12-02' OVERWRITE into table dw_ods.ods_base_region;"
2.2.2 业务数据装载
注意1：要在Sqoop数据同步成功之后运行。
注意2：crontab无法直接处理任务依赖关系！
TODO：如何判定Sqoop同步成功？？？？ 如何在其成功后运行？？？
（1） 开发脚本
[hadoop@hadoop102 ~]$ cd /home/hadoop/bin/
[hadoop@hadoop102 bin]$ vim hdfs_to_ods_db.sh
脚本内容：
#!/bin/bash
APP=dw_ods
# 如果是输入的日期按照取输入日期；如果没输入日期取当前时间的前一天
if [ -n "$2" ] ;then
do_date=$2
else
do_date=`date -d "-1 day" +%F`

2.2.3 日志数据装载
（1） 开发脚本
[hadoop@hadoop102 ~]$ cd /home/hadoop/bin/
[hadoop@hadoop102 bin]$ vim hdfs_to_ods_log.sh
脚本内容：
#!/bin/bash
# 如果是输入的日期按照取输入日期；如果没输入日期取当前时间的前一天
if [ -n "$1" ] ;then
do_date=$1
else
do_date=`date -d "-1 day" +%F`
fi
echo ================== 日志日期为 $do_date ==================
sql="
load data inpath '/warehouse/applog/gmall/tracking_log/$do_date' into table dw_ods.ods_log_inc partition(dt='$do_date');
"
hive -e "$sql"
（2） 授予脚本执行权限
[hadoop@hadoop102 bin]$ chmod +x hdfs_to_ods_log.sh
（3） 定时调度
凌晨3点执行，要等昨天的日志数据同步完成。
关键是保证白天时数仓能查到昨天分区的数据。
[hadoop@hadoop102 ~]$ crontab -e
