Phoenix安装
环境要求
Hadoop，Zookeeper，HBase都安装完成下载
官网下载地址：http://phoenix.apache.org/download.html
找到对应HBase的版本上传到Master节点，解压并配置
$ tar -zxvf apache-phoenix-4.14.0-HBase-1.1-bin.tar.gz
环境变量
# For Phoenix
export PHOENIX_HOME=/home/hadoop/phoenix/apache-phoenix-4.14.0-HBase-1.1-bin
export PHOENIX_CLASSPATH=$PHOENIX_HOME
export PATH=$PHOENIX_HOME/bin:$PATH
- 拷贝jar包
进入到phoenix的安装目录，找到phoenix-4.14.0-HBase-1.1-server.jar，拷贝到HBase各个节点的$HBASE_HOME/lib下
==重新启动HBase==
- 启动phoenix
启动脚本sqlline.py，参数是Zookeeper节点
$ cd $PHOENIX_HOME/bin
$ sqlline.py zk01,zk02,zk03:2181

到这里我们就已经进入到 phoenix 的终端了
简单使用
使用官网上的一个例子来建表、导入数据、查询
安装包里有样例数据../example路径下

登录hbase的命令行界面时，会发现多了几张表
hbase(main):001:0> list

SYSTEM.CATALOG
SYSTEM.FUNCTION
SYSTEM.LOG
SYSTEM.MUTEX
SYSTEM.SEQUENCE
SYSTEM.STATS
WEB_STAT
使用SQL查询表

映射到存在的HBase表
创建一张hbase表
> create 't1', 'f'
> put 't1', "row1", 'f:q', 1
> put 't1', "row2", 'f:q', 2
> put 't1', "row3", 'f:q', 3
> put 't1', "row4", 'f:q', 4
> put 't1', "row5", 'f:q', 5
在phoenix建一张同样的表
t1、row、f、q 需要用双引号括起来，原因主要是大小写的问题
./sqlline.py localhost
CREATE TABLE IF NOT EXISTS "t1" (
"row" VARCHAR NOT NULL,
"f"."q" VARCHAR
CONSTRAINT PK PRIMARY KEY ("row")
);
可以使用SQL查询t1表
