#大数据

1 ODS层（用户行为数据）

1.1 创建日志表ods_log

建表语句

hive (gmall)> 
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
;

数据装载思路：

装载语句：

hive (gmall)> 
load data inpath '/origin_data/gmall/log/topic_log/2020-06-14' into table ods_log partition(dt='2020-06-14');

为lzo压缩文件创建索引

[zhang@hadoop102 bin]$ hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/common/hadoop-lzo-0.4.20.jar com.hadoop.compression.lzo.DistributedLzoIndexer /warehouse/gmall/ods/ods_log/dt=2020-06-14

1.2 ODS层日志表加载数据脚本

在hadoop102的/home/zhang/bin目录下创建脚本

[zhang@hadoop102 bin]$ vim hdfs_to_ods_log.sh

在脚本中编写如下内容

#!/bin/bash

# 定义变量方便修改
APP=gmall

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

hive -e "$sql"

hadoop jar /opt/module/hadoop-3.1.3/share/hadoop/common/hadoop-lzo-0.4.20.jar com.hadoop.compression.lzo.DistributedLzoIndexer /warehouse/$APP/ods/ods_log/dt=$do_date

增加权限：[zhang@hadoop102 bin]$ chmod +x hdfs_to_ods_log.sh

去datagrip执行以下刚刚写的建表语句

去执行装载脚本：

[zhang@hadoop102 bin]$ ./hdfs_to_ods_log.sh 2020-06-14

去datagrip中查看刚刚的数据有没有被写入

2 ODS层（业务数据）

粘贴到datagrip，并执行当前代码

执行完之后就可以做数据的装载了。

装载思路

2.2 ODS层业务表首日数据装载脚本

编写脚本

在/home/zhang/bin目录下创建脚本hdfs_to_ods_db_init.sh

[zhang@hadoop102 bin]$ vim hdfs_to_ods_db_init.sh

在脚本中填写如下内容

#!/bin/bash

APP=gmall

if [ -n "$2" ] ;then
   do_date=$2
else 
   echo "请传入日期参数"
   exit
fi 

ods_order_info="

2.3 ODS层业务表每日数据装载脚本

编写脚本

在/home/zhang/bin目录下创建脚本hdfs_to_ods_db.sh

[zhang@hadoop102 bin]$ vim hdfs_to_ods_db.sh

在脚本中填写如下内容

#!/bin/bash

APP=gmall

# 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`
