DWD 层主要完成的功能 :
A、日志结构回顾
页面埋点日志
A、数据
[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]
B、取出第一个 json 对象
hive (gmall)>
select get_json_object('[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]','$[0]');
结果是:{"name":"大郎","sex":"男","age":"25"}
C、取出第一个 json 的 age 字段的值
hive (gmall)>
SELECT get_json_object('[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]',"$[0].age");
结果是:25
启动日志解析思路:启动日志表中每行数据对应一个启动记录,一个启动记录应该包含日志中的公共信息和启动信息。先将所有包含start字段的日志过滤出来,然后使用get_json_object函数解析每个字段。
A、建表语句
DROP TABLE IF EXISTS dwd_start_log;
CREATE EXTERNAL TABLE dwd_start_log(
`area_code` STRING COMMENT '地区编码',
`brand` STRING COMMENT '手机品牌',
`channel` STRING COMMENT '渠道',
`is_new` STRING COMMENT '是否首次启动',
`model` STRING COMMENT '手机型号',
`mid_id` STRING COMMENT '设备id',
`os` STRING COMMENT '操作系统',
`user_id` STRING COMMENT '会员id',
`version_code` STRING COMMENT 'app版本号',
`entry` STRING COMMENT 'icon手机图标 notice 通知 install 安装后启动',
`loading_time` BIGINT COMMENT '启动加载时间',
`open_ad_id` STRING COMMENT '广告页ID ',
`open_ad_ms` BIGINT COMMENT '广告总共播放时间',
`open_ad_skip_ms` BIGINT COMMENT '用户跳过广告时点',
`ts` BIGINT COMMENT '时间'
) COMMENT '启动日志表'
PARTITIONED BY (`dt` STRING) -- 按照时间创建分区
STORED AS PARQUET -- 采用parquet列式存储
LOCATION '/warehouse/gmall/dwd/dwd_start_log' -- 指定在HDFS上存储位置
TBLPROPERTIES('parquet.compression'='lzo') -- 采用LZO压缩
;
B、数据导入
hive (gmall)>
insert overwrite table dwd_start_log partition(dt='2020-06-14')
select
get_json_object(line,'$.common.ar'),
get_json_object(line,'$.common.ba'),

get_json_object(line,'$.ts')
from ods_log
where dt='2020-06-14'
and get_json_object(line,'$.start') is not null;
C、查看数据
hive (gmall)>
select * from dwd_start_log where dt='2020-06-14' limit 2;
页面日志解析思路:页面日志表中每行数据对应一个页面访问记录,一个页面访问记录应该包含日志中的公共信息和页面信息。先将所有包含 page 字段的日志过滤出来,然后使用 get_json_object 函数解析每个字段。
页面日志表解析:
A、建表语句
DROP TABLE IF EXISTS dwd_page_log;
CREATE EXTERNAL TABLE dwd_page_log(
`area_code` STRING COMMENT '地区编码',
`brand` STRING COMMENT '手机品牌',
`channel` STRING COMMENT '渠道',
`is_new` STRING COMMENT '是否首次启动',

`page_item_type` STRING COMMENT '目标类型',
`last_page_id` STRING COMMENT '上页类型',
`page_id` STRING COMMENT '页面ID ',
`source_type` STRING COMMENT '来源类型',
`ts` bigint
) COMMENT '页面日志表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET

TBLPROPERTIES('parquet.compression'='lzo');
B、数据导入
hive (gmall)>
insert overwrite table dwd_page_log partition(dt='2020-06-14')
select
get_json_object(line,'$.common.ar'),
get_json_object(line,'$.common.ba'),

get_json_object(line,'$.page.item_type'),
get_json_object(line,'$.page.last_page_id'),
get_json_object(line,'$.page.page_id'),
get_json_object(line,'$.page.source_type'),
get_json_object(line,'$.ts')
from ods_log
where dt='2020-06-14'
and get_json_object(line,'$.page') is not null;
C、查看数据
hive (gmall)>
select * from dwd_page_log where dt='2020-06-14' limit 2;
动作日志解析思路:动作日志表中每行数据对应用户的一个动作记录,一个动作记录应当包含公共信息、页面信息以及动作信息。先将包含action字段的日志过滤出来,然后通过 UDTF 函数,将action数组 “炸开”(类似于explode函数的效果),然后使用 get_json_object 函数解析每个字段。

B、创建 UDTF 函数 —— 设计思路
UDTF 思想:
C、创建UDTF函数 —— 编写代码
(1)创建一个 maven 工程:hivefunction
(2)创建包名:com.fancy.hive.udtf
(3)引入如下依赖
<dependencies>
<dependency>
<groupId>org.apache.hivegroupId>
<artifactId>hive-execartifactId>
<version>3.1.2version>
dependency>
dependencies>
(4)编码
package com.fancy.hive.udtf;
import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
import org.apache.hadoop.hive.ql.metadata.HiveException;
import org.apache.hadoop.hive.ql.udf.generic.GenericUDTF;
import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorFactory;
import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
import org.apache.hadoop.hive.serde2.objectinspector.StructObjectInspector;
import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
import org.json.JSONArray;
import java.util.ArrayList;
import java.util.List;
public class ExplodeJSONArray extends GenericUDTF {
@Override
public StructObjectInspector initialize(ObjectInspector[] argOIs) throws UDFArgumentException {
// 1 参数合法性检查
if (argOIs.length != 1) {
throw new UDFArgumentException("explode_json_array 只需要一个参数");
}
// 2 第一个参数必须为string
//判断参数是否为基础数据类型
if (argOIs[0].getCategory() != ObjectInspector.Category.PRIMITIVE) {
throw new UDFArgumentException("explode_json_array 只接受基础类型参数");
}
//将参数对象检查器强转为基础类型对象检查器
PrimitiveObjectInspector argumentOI = (PrimitiveObjectInspector) argOIs[0];
//判断参数是否为String类型
if (argumentOI.getPrimitiveCategory() != PrimitiveObjectInspector.PrimitiveCategory.STRING) {
throw new UDFArgumentException("explode_json_array 只接受string类型的参数");
}
// 3 定义返回值名称和类型
List<String> fieldNames = new ArrayList<String>();
List<ObjectInspector> fieldOIs = new ArrayList<ObjectInspector>();
fieldNames.add("items");
fieldOIs.add(PrimitiveObjectInspectorFactory.javaStringObjectInspector);
return ObjectInspectorFactory.getStandardStructObjectInspector(fieldNames, fieldOIs);
}
public void process(Object[] objects) throws HiveException {
// 1 获取传入的数据
String jsonArray = objects[0].toString();
// 2 将string转换为json数组
JSONArray actions = new JSONArray(jsonArray);
// 3 循环一次,取出数组中的一个json,并写出
for (int i = 0; i < actions.length(); i++) {
String[] result = new String[1];
result[0] = actions.getString(i);
forward(result);
}
}
public void close() throws HiveException {
}
}
D、创建函数
(1)打包
(2)将 hivefunction-1.0-SNAPSHOT.jar 上传到 node101 的 /opt/module,然后再将该 jar 包上传到 HDFS 的 /user/hive/jars 路径下
[fancy@node101 module]$ hadoop fs -mkdir -p /user/hive/jars
[fancy@node101 module]$ hadoop fs -put hivefunction-1.0-SNAPSHOT.jar /user/hive/jars
(3)创建永久函数与开发好的java class关联
create function explode_json_array as 'com.fancy.hive.udtf.ExplodeJSONArray' using jar 'hdfs://hadoop102:8020/user/hive/jars/hivefunction-1.0-SNAPSHOT.jar';
注意:
如果修改了自定义函数重新生成 jar 包怎么处理?只需要替换HDFS 路径上的旧 jar 包,然后重启 Hive 客户端即可。
E、数据导入
insert overwrite table dwd_action_log partition(dt='2020-06-14')
select
get_json_object(line,'$.common.ar'),
get_json_object(line,'$.common.ba'),
get_json_object(line,'$.common.ch'),
get_json_object(line,'$.common.is_new'),
get_json_object(line,'$.common.md'),
get_json_object(line,'$.common.mid'),

get_json_object(line,'$.page.last_page_id'),
get_json_object(line,'$.page.page_id'),
get_json_object(line,'$.page.source_type'),
get_json_object(action,'$.action_id'),
get_json_object(action,'$.item'),
get_json_object(action,'$.item_type'),
get_json_object(action,'$.ts')
from ods_log lateral view explode_json_array(get_json_object(line,'$.actions')) tmp as action
where dt='2020-06-14'
and get_json_object(line,'$.actions') is not null;
F、查看数据
select * from dwd_action_log where dt='2020-06-14' limit 2;
曝光日志解析思路:曝光日志表中每行数据对应一个曝光记录,一个曝光记录应当包含公共信息、页面信息以及曝光信息。先将包含 display 字段的日志过滤出来,然后通过 UDTF 函数,将 display 数组 “炸开”(类似于 explode 函数的效果),然后使用 get_json_object 函数解析每个字段。
曝光日志表解析
A、建表语句

C、查看数据
select * from dwd_display_log where dt='2020-06-14' limit 2;
错误日志解析思路:错误日志表中每行数据对应一个错误记录,为方便定位错误,一个错误记录应当包含与之对应的公共信息、页面信息、曝光信息、动作信息、启动信息以及错误信息。先将包含err字段的日志过滤出来,然后使用 get_json_object 函数解析所有字段。
A、建表语句
DROP TABLE IF EXISTS dwd_error_log;
CREATE EXTERNAL TABLE dwd_error_log(
`area_code` STRING COMMENT '地区编码',

说明:此处为对动作数组和曝光数组做处理,如需分析错误与单个动作或曝光的关联,可先使用 explode_json_array 函数将数组“炸开”,再使用get_json_object 函数获取具体字段。
D、数据导入

业务数据方面DWD层的搭建主要注意点在于维度建模。
A、建表语句
DROP TABLE IF EXISTS dwd_comment_info;
CREATE EXTERNAL TABLE dwd_comment_info(
`id` STRING COMMENT '编号',
`user_id` STRING COMMENT '用户ID',
`sku_id` STRING COMMENT '商品sku',
`spu_id` STRING COMMENT '商品spu',
`order_id` STRING COMMENT '订单ID',
`appraise` STRING COMMENT '评价(好评、中评、差评、默认评价)',
`create_time` STRING COMMENT '评价时间'
) COMMENT '评价事实表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET
LOCATION '/warehouse/gmall/dwd/dwd_comment_info/'

B、分区规划
C、数据装载
insert overwrite table dwd_comment_info partition (dt)
select
