上文访问:离线数仓搭建_10_DIM层维度层数据导入
下文访问:离线数仓搭建_12_DWD层业务数据创建
1)对用户行为数据解析。
2)对业务数据采用维度模型重新建模。
1)日志结构回顾
(1)页面埋点日志
(2)启动日志
2)日志解析思路
1)数据
[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]
2)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"}]','$[0]');
结果是:{“name”:“大郎”,“sex”:“男”,“age”:“25”}
3)取出第一个json的age字段的值
hive (gmall)>
SELECT get_json_object('[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]',"$[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。
1)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',

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。

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。
1)建表语句

2)创建UDTF函数——设计思路
3)创建UDTF函数——编写代码
(1)创建一个maven工程:hivefunction
(2)创建包名:com.atguigu.hive.udtf
(3)引入如下依赖
org.apache.hive
hive-exec
3.1.2
(4)编码
package com.atguigu.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 {
}
}
4)创建函数
(1)打包
(2)将hivefunction-1.0-SNAPSHOT.jar上传到hadoop102的/opt/module,然后再将该jar包上传到HDFS的/user/hive/jars路径下
[atguigu@hadoop102 module]$ hadoop fs -mkdir -p /user/hive/jars
[atguigu@hadoop102 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.atguigu.hive.udtf.ExplodeJSONArray' using jar 'hdfs://hadoop102:8020/user/hive/jars/hivefunction-1.0-SNAPSHOT.jar';
(4)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。
5)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'),

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;
3)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。
1)建表语句

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。

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。
