问题
分析
应用场景:应用系统或者大数据存储系统
大数据存储系统:大数据工程师
应用系统:Java工程师、数据分析师
问题:Java人员不会Hbase Java API,对于数据库会JDBC
解决:需要一个工具能让Hbase支持SQL,支持JDBC方式对Hbase进行处理
Hbase的结构是否能实现基于SQL的查询操作?
普通表数据:按行操作
id name age sex addr
001 zhangsan 18 null shanghai
002 lisi 20 female null
003 wangwu null male beijing
……
Hbase数据:按列操作
rowkey cf1:id cf1:name cf1:age cf2:sex cf2:addr
zhangsan_001 001 zhangsan 18 null shanghai
lisi_002 002 lisi 20 female null
wangwu_003 003 wangwu null male beijing
……
可以基于Hbase数据构建结构化的数据形式
可以用SQL来实现处理
实现
总结
功能:实现Hive与Hbase集成,使用Hive SQL对Hbase的数据进行处理
原理
Hive的功能:使用HQL对表的数据进行处理
本质:通过MapReduce对HDFS中的文件进行处理
原理
TextInputFormat:读文件
TextOutputFormat:写文件
MapReduce的功能:读取数据进行分布式计算
InputFormat:输入类
OutputFormat:输出类
TextOutputFormat:默认的输出类,用于将结果写入文件系统
DBOutputFormat:用于写入JDBC数据库
TableOutputFormat:用于写入HBase数据库
原理:Hive可以通过MapReduce来实现映射读写Hbase表的数据
特点
优点:支持完善的SQL语句,可以实现各种复杂SQL的数据处理及计算,通过分布式计算程序实现,对大数据量的数据处理比较友好
缺点:不支持二级索引,数据量不是特别大的情况下,性能一般

全部操作在第三台机器
修改hive-site.xml:Hive通过SQL访问Hbase,就是Hbase的客户端,就要连接zookeeper

修改hive-env.sh
export HBASE_HOME=/export/server/hbase-2.1.0
启动HDFS、ZK、Hbase:第一台机器
start-dfs.sh
/export/server/zookeeper-3.4.6/bin/start-zk-all.sh

第三台机器测试
如果Hbase中表不存在:【用的比较少】
创建测试数据文件
vim /export/data/hive-hbase.txt
1,zhangsan,80
2,lisi,60
3,wangwu,30
4,zhaoliu,70
创建测试表
--创建测试数据库
create database course;
--切换数据库
use course;
--创建原始数据表
create external table if not exists course.score(
id int,
cname string,
score int
) row format delimited fields terminated by ',' stored as textfile ;
--加载数据文件
load data local inpath '/export/data/hive-hbase.txt' into table score;
创建一张Hive与HBASE的映射表
create table course.hbase_score(
id int,
cname string,
score int
)
stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
with serdeproperties("hbase.columns.mapping" = "cf:name,cf:score")
tblproperties("hbase.table.name" = "hbase_score");
将测试表的数据写入映射表
set hive.exec.mode.local.auto=true;
insert overwrite table course.hbase_score select id,cname,score from course.score;
如果Hbase中表已存在,只能创建外部表
create external table course.t1(
key string,
name string,
age string,
addr string,
phone string
)
stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
with serdeproperties("hbase.columns.mapping" = ":key,basic:name,basic:age,other:addr,other:phone")
tblproperties("hbase.table.name" = "itcast:t1");

总结
在Hive中创建Hbase的关联表,关联成功后,使用SQL处理关联表

分析
step1:基于存储和常用查询需求,构建数据表
step2:基于其他查询需求,构建索引表
step3:先查询索引表,再查询数据表
step4:自动维护索引表与原始数据表的数据一致性

创建
语法:http://phoenix.apache.org/language/index.html#create_table
CREATE TABLE my_schema.my_table (
id BIGINT not null primary key,
date Date
);
CREATE TABLE my_table (
id INTEGER not null primary key desc,
m.date DATE not null,
m.db_utilization DECIMAL,
i.db_utilization
) m.VERSIONS='3';
CREATE TABLE stats.prod_metrics (

如果Hbase中没有这个表
use default;
create table if not exists ORDER_DTL(

C1.STATUS varchar,
C1.PAY_MONEY float,
C1.PAYWAY integer,
C1.USER_ID varchar,

如果Hbase中已存在会自动关联
create table if not exists ORDER_INFO(
"ROW" varchar primary key,
"C1"."USER_ID" varchar,
"C1"."OPERATION_DATE" varchar,
"C1"."PAYWAY" varchar,
"C1"."PAY_MONEY" varchar,
"C1"."STATUS" varchar,
"C1"."CATEGORY" varchar
) column_encoded_bytes=0 ;
查看
!desc order_info;
删除
drop table if exists order_dtl;
总结
创建表时,必须指定主键作为Rowkey,主键列不能加列族
create table if not exists ORDER_INFO(
–不能这么写
“C1”.“ROW” varchar primary key,
“C1”.“USER_ID” varchar,
“C1”.“OPERATION_DATE” varchar,
“C1”.“PAYWAY” varchar,
“C1”.“PAY_MONEY” varchar,
“C1”.“STATUS” varchar,
“C1”.“CATEGORY” varchar
) column_encoded_bytes=0 ;
- Phoenix 4.8版本之前只要创建同名的Hbase表,会自动关联数据
- Phoenix 4.8版本以后,不推荐关联表的方式
- 推荐使用视图关联的方式来实现,如果你要使用关联表的方式,必须加上以下参数
```
column_encoded_bytes=0 ;
```
- 如果关联已存在的表,Rowkey字段叫做ROW,使用时必须加上双引号
select “ROW”,“C1”.USER_ID,“C1”.“PAYWAY” from ORDER_INFO;

查询支付方式为1的数据
select "ROW",payway,pay_money,category from order_info where payway = '1';
查询每种支付方式对应的用户人数,并且按照用户人数降序排序

group by payway
order by numb desc;
查询数据的第60行到66行
--以前的写法:limit M,N

总结
实现效果与命令实现的效果一致
通过SQL建表语句实现
create table() split
需求
分析
在Phoenix创建一张盐表,写入的数据会自动进行编码写入不同的分区中
CREATE TABLE table (
a_key VARCHAR PRIMARY KEY,
a_col VARCHAR
) SALT_BUCKETS = 20;
实现
创建一张盐表,指定分区个数为10
drop table if exists ORDER_DTL;
create table if not exists ORDER_DTL(
"id" varchar primary key,
C1."status" varchar,
C1."money" float,
C1."pay_way" integer,
C1."user_id" varchar,
C1."operation_time" varchar,
C1."category" varchar
)
CONPRESSION='GZ', SALT_BUCKETS=10;

Phoenix中查看
select "id" from ORDER_DTL;
Hbase中查看
scan 'ORDER_DTL'
总结
需求
分析
实现
创建视图,关联Hbase中已经存在的表
create view if not exists "MOMO_CHAT"."MSG" (
"pk" varchar primary key, -- 指定ROWKEY映射到主键
"C1"."msg_time" varchar,
"C1"."sender_nickyname" varchar,
"C1"."sender_account" varchar,
"C1"."sender_sex" varchar,
"C1"."sender_ip" varchar,
"C1"."sender_os" varchar,
"C1"."sender_phone_type" varchar,
"C1"."sender_network" varchar,
"C1"."sender_gps" varchar,
"C1"."receiver_nickyname" varchar,
"C1"."receiver_ip" varchar,
"C1"."receiver_account" varchar,
"C1"."receiver_os" varchar,
"C1"."receiver_phone_type" varchar,
"C1"."receiver_network" varchar,
"C1"."receiver_gps" varchar,
"C1"."receiver_sex" varchar,
"C1"."msg_type" varchar,
"C1"."distance" varchar
);
查询数据
select
"pk",
"C1"."msg_time",
"C1"."sender_account",
"C1"."receiver_account"
from "MOMO_CHAT"."MSG"
limit 10;
总结
需求
分析
Phoenix支持使用JDBC的方式来提交SQL语句
例如:聊天分析案例中需求:查询条件为日期【年-月-日】 + 发送人ID + 接受人ID
select
*
from "MOMO_CHAT"."MSG"
where
substr("msg_time",0,10) = '2021-03-22'
and "sender_account" = '17351912952'
and "receiver_account" = '17742251415';
可以在代码中基于JDBC来提交SQL查询
实现
构建JDBC连接Phoenix
package cn.itcast.momo_chat.service.impl;
import cn.itcast.momo_chat.entity.Msg;
import cn.itcast.momo_chat.service.ChatMessageService;
import org.apache.phoenix.jdbc.PhoenixDriver;
import java.sql.*;
import java.util.ArrayList;
import java.util.List;
/**
* @ClassName PhoenixChatMessageService
* @Description TODO JDBC连接Phoenix实现数据查询
* @Create By Frank
*/
public class PhoenixChatMessageService implements ChatMessageService {
private Connection connection;
public PhoenixChatMessageService() throws ClassNotFoundException, SQLException {
try {
//申明驱动类
Class.forName(PhoenixDriver.class.getName());
// System.out.println(PhoenixDriver.class.getName());
//构建连接
connection = DriverManager.getConnection("jdbc:phoenix:node1,node2,node3:2181");
} catch (ClassNotFoundException e) {
throw new RuntimeException("加载Phoenix驱动失败!");
} catch (SQLException e) {
throw new RuntimeException("获取Phoenix JDBC连接失败!");
}
}
@Override
public List<Msg> getMessage(String date, String sender, String receiver) throws Exception {
PreparedStatement ps = connection.prepareStatement(
"SELECT * FROM MOMO_CHAT.MSG T WHERE substr(\"msg_time\", 0, 10) = ? "
+ "AND T.\"sender_account\" = ? "
+ "AND T.\"receiver_account\" = ? ");
ps.setString(1, date);
ps.setString(2, sender);
ps.setString(3, receiver);
ResultSet rs = ps.executeQuery();
List<Msg> msgList = new ArrayList<>();
while(rs.next()) {
Msg msg = new Msg();
msg.setMsg_time(rs.getString("msg_time"));
msg.setSender_nickyname(rs.getString("sender_nickyname"));
msg.setSender_account(rs.getString("sender_account"));
msg.setSender_sex(rs.getString("sender_sex"));
msg.setSender_ip(rs.getString("sender_ip"));
msg.setSender_os(rs.getString("sender_os"));
msg.setSender_phone_type(rs.getString("sender_phone_type"));
msg.setSender_network(rs.getString("sender_network"));
msg.setSender_gps(rs.getString("sender_gps"));
msg.setReceiver_nickyname(rs.getString("receiver_nickyname"));
msg.setReceiver_ip(rs.getString("receiver_ip"));
msg.setReceiver_account(rs.getString("receiver_account"));
msg.setReceiver_os(rs.getString("receiver_os"));
msg.setReceiver_phone_type(rs.getString("receiver_phone_type"));

msg.setMsg_type(rs.getString("msg_type"));
msg.setDistance(rs.getString("distance"));
msgList.add(msg);
}
return msgList;
}
@Override
public void close() {
try {
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws Exception {
ChatMessageService chatMessageService = new PhoenixChatMessageService();
List<Msg> message = chatMessageService.getMessage("2021-03-22", "17351912952", "17742251415");
for (Msg msg : message) {
System.out.println(msg);
}
chatMessageService.close();
}
}
运行查看结果
