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) 授予脚本执行权限
[hadoop@hadoop102 bin]$ chmod +x hdfs_to_ods_db.sh
(3) 定时调度

每天凌晨3点装载业务数据

[hadoop@hadoop102 ~]$ crontab -e

新增内容:

# 每天凌晨3点装载业务数据
0 3 * * * hdfs_to_ods_db.sh all

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

新增内容:

# 每天凌晨3点装载用户日志数据增量表
0 3 * * * hdfs_to_ods_log.sh
