Apache Phoenix 官方站点:https://phoenix.apache.org/
Phoenix支持的sql语句:https://phoenix.apache.org/language/index.html

0. 软件版本下载

http://archive.apache.org/dist/phoenix/

1. 集群环境

Master 192.168.40.130
Slave1 192.168.40.131
Slave2 192.168.40.132

2. 下载软件包

#Master
]# wget http://mirror.bit.edu.cn/apache/phoenix/apache-phoenix-4.14.0-HBase-1.3/bin/apache-phoenix-4.14.0-HBase-1.3-bin.tar.gz
]# tar zxvf apache-phoenix-4.14.0-HBase-1.3-bin.tar.gz

3. 配置环境变量

#vim /etc/profile
#set phoenix environment
export PHOENIX_HOME=/usr/local/src/apache-phoenix-4.14.0-HBase-1.3-bin
PATH=${PHOENIX_HOME}/bin:$PATH

#安装 python-argparse 解析模块
]# yum install python-argparse

4. 分发phoenix的驱动

参考:https://phoenix.apache.org/Phoenix-in-15-minutes-or-less.html

#master
#分发phoenix-4.14.0-HBase-1.3-server.jar  
]# cd /usr/local/src/apache-phoenix-4.14.0-HBase-1.3-bin
]# cp phoenix-4.14.0-HBase-1.3-server.jar  /usr/local/src/hbase-1.3.1/lib/
]# scp phoenix-4.14.0-HBase-1.3-server.jar root@slave1:/usr/local/src/hbase-1.3.1/lib/
]# scp phoenix-4.14.0-HBase-1.3-server.jar root@slave2:/usr/local/src/hbase-1.3.1/lib/

5.重启Hbase

]# cd /usr/local/src/hbase-1.3.1/bin
]# ./stop-hbase.sh
]# ./start-hbase.sh

6.验证

• hbase中创建表

]# cd usr/local/src/hbase-1.3.1/bin
]# hbase shell
create  'person','basicinfo'
put 'person','1', 'basicinfo:name', 'uwoer'
put 'person','1', 'basicinfo:age', '24'
scan 'person'

• 进入phoenix命令行

]# cd /usr/local/src/apache-phoenix-4.14.0-HBase-1.3-bin/bin
sqlline.py localhost 或 sqlline.py master,slave1,slave2:2181

• phoenix中创建视图映射（view 只读）

create view "person" ("ROW" varchar primary key,"basicinfo"."name" varchar,"basicinfo"."age" varchar);
select * from "person";

• 创建完视图后再次查看hbase中表的信息

• view只读验证

UPSERT INTO "person"  VALUES('1','uwo','30');

• phoenix 中删除视图

drop view "person";

• 再次查看hbase中表的信息 person 依然存在

• phoenix 中创建映射表(table 读写)

create table "person" ("ROW" varchar primary key,"basicinfo"."name" varchar,"basicinfo"."age" varchar);
select * from "person";

• 创建完表后再次查看hbase中表的信息

多了一个映射信息：column=basicinfo:_0

• phoenix中写验证

UPSERT INTO "person"  VALUES('1','uwo','30');
select * from "person";

这个时候如果在phoenix删除表会同时删除hbase中的表

phoenix和hbase中非字符串类型的字段映射会有些问题，在通过api写数据的时候需要经过特殊处理
具体情况参考HBase和Phoenix的类型转换:https://blog.csdn.net/rewerma/article/details/80254876
