从hbase到hive，以及sqoop转到mysql解析

https://blog.csdn.net/qq_33689414/article/details/80328665　　hive关联hbase的配置文件

hive和hbase同步
https://cwiki.apache.org/confluence/display/Hive
https://cwiki.apache.org/confluence/display/Hive/HBaseIntegration

1、在hive的配置文件增加属性：hive-site.xml
<property>
<name>hbase.zookeeper.quorum</name>
<value>master:2181,node1:2181,node2:2181</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>master,node1,node2</value>
</property>

1.1.2 修改hive-env.sh文件

添加一个环境变量
export HIVE_CLASSPATH=$HIVE_CLASSPATH:/hadoop/hbase/lib/*

2、在hive中创建临时表
一、
CREATE TABLE hbasetbl(key int, value string)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'/存储格式的jar包
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")//serdeproperties 属性 一一对应
TBLPROPERTIES ("hbase.table.name" = "xyz", "hbase.mapred.output.outputtable" = "xyz");//输出表名

二、
put 'xyz','1111','cf1:name','zhangsan'
put 'xyz','1111','cf1:val','lisi'

三、
set hive.exec.mode.local.auto=true;  //设置为本地模式
insert into hbasetbl values(222,'wangwu');

查看hdfs

hbase> flush 'xyz'  //执行刷新后，hdfs才会同步

3.
一、
CREATE EXTERNAL TABLE tmp_order
(key string, id string, user_id string)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,order:order_id,order:user_id")
TBLPROPERTIES ("hbase.table.name" = "t_order");

外部表必须先在hbase建立表(在hive删除这个表会有什么影响？)
二、
create 't_order','order'

在执行
CREATE EXTERNAL TABLE tmp_order
(key string, id string, user_id string)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,order:order_id,order:user_id")
TBLPROPERTIES ("hbase.table.name" = "t_order");

put 't_order','1','order:order_id','1'
put 't_order','1','order:user_id','1'
select * from tmp_order;

hive
insert into tmp_order values(2,2,2);

一、两个角度
1.用户
2.会话

二、mysql数据表
stats_view_depth

CREATE TABLE `stats_view_depth` (
`platform_dimension_id` bigint ,
`data_dimension_id` bigint ,
`kpi_dimension_id` bigint ,
`pv1` bigint ,
`pv2` bigint ,
`pv3` bigint ,
`pv4` bigint ,
`pv5_10` bigint ,
`pv10_30` bigint ,
`pv30_60` bigint ,
`pv60_plus` bigint ,
`created` string
) row format delimited fields terminated by '\t';

三、数据
1.用户ID
2.时间
3.URL
4.PV

四、HIVE和HBASE对应关系

set hive.exec.mode.local.auto=true;

1.在hive中创建hbase的event_log对应表
CREATE EXTERNAL TABLE event_logs(
key string, pl string, en string, s_time bigint, p_url string, u_ud string, u_sd string
) ROW FORMAT SERDE 'org.apache.hadoop.hive.hbase.HBaseSerDe'
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
with serdeproperties('hbase.columns.mapping'=':key,log:pl,log:en,log:s_time,log:p_url,log:u_ud,log:u_sd')
tblproperties('hbase.table.name'='eventlog');

分组条件
UUID
PL
count(url):1,2,3,4.... (hive_case_when)

3.hive创建临时表:把hql分析之后的中间结果存放到当前的临时表。
CREATE TABLE `stats_view_depth_tmp`(`pl` string, `date` string, `col` string, `ct` bigint);

然后先看第七步的操作SQL，再回头看udf

-- 4. 编写UDF(platformdimension & datedimension)

package com.yjsj.transformer.hive;

import com.yjsj.common.DateEnum;
import com.yjsj.transformer.model.dim.base.DateDimension;
import com.yjsj.transformer.model.dim.base.PlatformDimension;
import com.yjsj.transformer.service.IDimensionConverter;
import com.yjsj.transformer.service.impl.DimensionConverterImpl;
import com.yjsj.util.TimeUtil;
import org.apache.hadoop.hive.ql.exec.UDF;
import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.Text;

import java.io.IOException;

/**
 * 操作日期dimension 相关的udf
 *
 * @author root
 *
 */
public class PlatformDimensionUDF extends UDF {
    private IDimensionConverter converter = new DimensionConverterImpl();

    /**
     * 根据给定的日期（格式为:yyyy-MM-dd）至返回id
     *
     * @param pl
     * @return
     */
    public IntWritable evaluate(Text pl) {
        PlatformDimension dimension = new PlatformDimension(pl.toString());
        try {
            int id = this.converter.getDimensionIdByValue(dimension);
            return new IntWritable(id);
        } catch (IOException e) {
            throw new RuntimeException("获取id异常");
        }
    }
}

package com.yjsj.transformer.hive;

import java.io.IOException;

import org.apache.hadoop.hive.ql.exec.UDF;
import org.apache.hadoop.io.IntWritable;
import org.apache.hadoop.io.Text;

import com.yjsj.common.DateEnum;
import com.yjsj.transformer.model.dim.base.DateDimension;
import com.yjsj.transformer.service.IDimensionConverter;
import com.yjsj.transformer.service.impl.DimensionConverterImpl;
import com.yjsj.util.TimeUtil;

/**
 * 操作日期dimension 相关的udf
 *
 * @author root
 *
 */
public class DateDimensionUDF extends UDF {
    private IDimensionConverter converter = new DimensionConverterImpl();

    /**
     * 根据给定的日期（格式为:yyyy-MM-dd）至返回id
     *
     * @param day
     * @return
     */
    public IntWritable evaluate(Text day) {
        DateDimension dimension = DateDimension.buildDate(TimeUtil.parseString2Long(day.toString()), DateEnum.DAY);
        try {
            int id = this.converter.getDimensionIdByValue(dimension);
            return new IntWritable(id);
        } catch (IOException e) {
            throw new RuntimeException("获取id异常");
        }
    }
}

底层dimension在项目内

-- 5. 上传transformer.jar到hdfs的/yjsj/transformer文件夹中

文件夹放到虚拟机上之后要执行

zip -d wc.jar 'META-INF/.SF' 'META-INF/.RSA' 'META-INF/*SF'

hadoop fs -mkdir -p /yjsj/transformer

hadoop fs -put transformer.jar  /yjsj/transformer/
-- 6. 创建hive的function

#create function platform_convert as 'com.yjsj.transformer.hive.PlatformDimensionUDF' using jar 'hdfs://master:9000/yjsj/transformer/transformer.jar';
create function date_convert  as 'com.yjsj.transformer.hive.DateDimensionUDF' using jar 'hdfs://master:9000/yjsj/transformer/transformer.jar';

create function platform_convert as 'com.yjsj.transformer.hive.PlatformDimensionUDF' using jar 'hdfs://master:9000/yjsj/transformer/BIG_DATA_SXT_3.jar';
create function date_convert as 'com.yjsj.transformer.hive.DateDimensionUDF' using jar 'hdfs://master:9000/yjsj/transformer/BIG_DATA_SXT_3.jar';

 上面的端口号9000要写上，在之前的hive文档里并没有写，如下，是因为默认是8020，而我们修改为9000

7. hql编写(统计用户角度的浏览深度)<注意：时间为外部给定>
select
pl, from_unixtime(cast(s_time/1000 as bigint),'yyyy-MM-dd') as day, u_ud
from event_logs
where

and p_url is not null
and pl is not null
and s_time >= unix_timestamp('2019-04-08','yyyy-MM-dd')*1000
and s_time < unix_timestamp('2019-04-09','yyyy-MM-dd')*1000;

下面是上句生成结果（为方便后续综合代码理解，才写的这行SQL语句）

and p_url is not null
and pl is not null
and s_time >= unix_timestamp('2019-04-08','yyyy-MM-dd')*1000

group by

) as tmp
insert overwrite table stats_view_depth_tmp
select pl,day,pv,count(u_ud) as ct where u_ud is not null group by pl,day,pv;

select * from stats_view_depth_tmp;

结果如下

website 2019-04-08 pv1 9
website 2019-04-08 pv2 10
website 2019-04-08 pv3 5
website 2019-04-08 pv4 2
website 2019-04-08 pv5_10 1

因为我们需要的内容格式如下

所以之后进行行转列
--把临时表的多行数据，转换一行

UNION 内部的每个 SELECT 语句必须拥有相同数量的列。列也必须拥有相似的数据类型。同时，每个 SELECT 语句中的列的顺序必须相同。

根据where语句筛选要合并的内容项

下面则是没有定义UDF时候把下面的select 语句替换掉上面的

select 2,1,6,sum(pv1),sum(pv2),sum(pv3),sum(pv4),sum(pv5_10),sum(pv10_30),sum(pv30_60),sum(pv60_plus),'2019-04-08' group by pl,date1;

查询结果

select * from stats_view_depth;

  //上面的前三项

platform_convert(pl),date_convert(date1),6,分别是平台维度id，日期维度id，kpi维度id

而前两项，即平台和日期维度，是通过前面四定义的udf函数来转换的，底层是写的java语句，

（1）继承 org.apache.hadoop.hive.ql.UDF
（2）需要实现 evaluate 函数；evaluate 函数支持重载；
（3）在 hive 的命令行窗口创建函数
a）添加 jar
add jar linux_jar_path b）创
建 function，
create [temporary] function [dbname.]function_name AS class_name;
（4）在 hive 的命令行窗口删除函数
Drop [temporary] function [if exists] [dbname.]function_name; 6）注
意事项
（1）UDF 必须要有返回类型，可以返回 null，但是返回类型不能为 void
