[大数据]数据仓库搭建ODS层

目录

一、用户行为数据

1.1创建日志表

1.2ODS层加载数据脚本

二、业务数据

2.1hive建表

2.2ODS层加载数据脚本

一、用户行为数据

1.1创建日志表

1）创建支持lzo压缩的分区表

drop table if exists ods_log;
CREATE EXTERNAL TABLE ods_log (`line` string)
PARTITIONED BY (`dt` string) -- 按照时间创建分区
STORED AS -- 指定存储方式，读数据采用LzoTextInputFormat；
  INPUTFORMAT 'com.hadoop.mapred.DeprecatedLzoTextInputFormat'
  OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION '/warehouse/gmall/ods/ods_log'  -- 指定数据在hdfs上的存储位置
;

2）加载数据

load data inpath '/data/log/topic_log/2021-05-10' into table ods_log partition(dt='2021-05-10');

3）查看是否加载成功

4）为lzo压缩文件创建索引

hadoop jar /training/hadoop-3.1.3/share/hadoop/common/hadoop-lzo-0.4.20.jar com.hadoop.compression.lzo.DistributedLzoIndexer -Dmapreduce.job.queuename=hive/warehouse/gmall/ods/ods_log/dt=2021-05-10

1.2ODS层加载数据脚本

vi hdfs_to_ods_log.sh

#!/bin/bash

# 定义变量方便修改
APP=default
hive=/training/hive/bin/hive
hadoop=/training/hadoop-3.1.3/bin/hadoop

# 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 $do_date ==================
sql="
load data inpath '/data/log/topic_log/$do_date' into table default.ods_log partition(dt='$do_date');
"

$hive -e "$sql"

hadoop jar /training/hadoop-3.1.3/share/hadoop/common/hadoop-lzo-0.4.20.jar
com.hadoop.compression.lzo.DistributedLzoIndexer -Dmapreduce.job.queuename=hive/warehouse/gmall/ods/ods_log/dt=$do_date

增加脚本执行权限：chmod 777 hdfs_to_ods_log.sh

脚本使用：hdfs_to_ods_log.sh 2020-06-15

查看导入数据：select * from ods_log where dt='2020-06-15' limit 2;

脚本执行时间：企业开发中一般在每日凌晨30分~1点

二、业务数据

2.1hive建表

修改权限：?chmod 777 hdfs_to_ods_db.sh

初次导入：初次导入时，脚本的第一个参数应为first，线上环境不传第二个参数，自动获取前一天日期

hdfs_to_ods_db.sh?first 2022-05-10

每日导入：每日重复导入，脚本的第一个参数应为all，线上环境不传第二个参数，自动获取前一天日期。

hdfs_to_ods_db.sh?all 2020-06-15

测试数据是否导入成功：select * from ods_order_detail where dt='2022-05-10';
