Apache Phoenix 是 HBase 的 SQL 驱动。Phoenix 使得 HBase 支持通过 JDBC 的方式进行访问,并将你的 SQL 查询转成 HBase 的扫描和相应的动作。
兼容性:
Phoenix 2.x - HBase 0.94.x
Phoenix 3.x - HBase 0.94.x
Phoenix 4.x - HBase 0.98.1+
1:hbase 0.94.21 的安装
2:下载phoenix 3.1
[linuxidc@linuxidc02 ~]# wget

3:解压
[linuxidc@linuxidc02 ~]$ tar zxf phoenix-3.1.0-bin.tar.gz
[linuxidc@linuxidc02 ~]$ cd phoenix-3.1.0-bin
[linuxidc@linuxidc02 phoenix-3.1.0-bin]$ ls

4:配置
参考:
我这里使用的是Phoenix 3.x
To install a pre-built phoenix, use these directions:
Download and expand the latest phoenix-[version]-bin.tar. Use either hadoop1 and hadoop2 artifacts which match your HBase installation.
下载,根据安装的HBase选择hadoop1或hadoop2
Add the phoenix-[version]-server.jar to the classpath of every HBase region server and remove any previous version. An easy way to do this is to copy it into the HBase lib directory (use phoenix-core-[version].jar for Phoenix 3.x)
把phoenix-core-3.1.0.jar复制到所有HBase region server的lib目录
Restart all region servers.
重启所有的Hbase region servers.
Add the phoenix-[version]-client.jar to the classpath of any Phoenix client.
Phoenix client服务器的CLASSPATH加上phoenix-3.1.0-client-hadoop1.jar
[linuxidc@linuxidc02 phoenix-3.1.0-bin]$ cd common
[linuxidc@linuxidc02 common]$ ls
phoenix-3.1.0-client-minimal.jar phoenix-3.1.0-client-without-hbase.jar phoenix-core-3.1.0.jar
[linuxidc@linuxidc02 common]$ cp ./phoenix-core-3.1.0.jar /home/linuxidc/hbase-0.94.21/lib
[linuxidc@linuxidc02 common]$ scp ./phoenix-core-3.1.0.jar linuxidc@linuxidc01:/home/linuxidc/hbase-0.94.21/lib
phoenix-core-3.1.0.jar 100% 2178KB 2.1MB/s 00:00
[linuxidc@linuxidc02 common]$ cd ..
在配置文件/home/linuxidc/.bash_profile中
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:/home/linuxidc/phoenix-3.1.0-bin/hadoop1/phoenix-3.1.0-client-hadoop1.jar
然后重启HBase
[linuxidc@linuxidc01 hbase-0.94.21]$ bin/stop-hbase.sh
stopping hbase................
linuxidc01: stopping zookeeper.
linuxidc02: stopping zookeeper.
[linuxidc@linuxidc01 hbase-0.94.21]$ bin/start-hbase.sh
