phoenix只是一个插件，我们可以用hive给hbase套上一个JDBC壳，但是你有没有体会到Hive执行SQL语句是很慢的，因此我们采用phoenix插件的方式给hbase套上JDBC的壳。
一.Phoenix简介
1>.其实Phoenix可以看成是在hbase的hive，它是使用SQL方式访问HBase数据；
2>.内置多种协处理器实现，轻松实现二级索引和聚合查询；
二.部署phoenix
1>.下载phoenix插件
下载地址：http://www.apache.org/dyn/closer.lua/phoenix/
2>.解压
[yinzhengjie@s101 data]$ tar zxf apache-phoenix-4.10.-HBase-1.2-bin.tar.gz -C /soft/
[yinzhengjie@s101 data]$
3>.创建软连接
[yinzhengjie@s101 data]$ ln -s /soft/apache-phoenix-4.10.-HBase-1.2-bin/ /soft/phoenix
[yinzhengjie@s101 data]$
4>.配置环境变量并使之生效
[yinzhengjie@s101 data]$ sudo vi /etc/profile
[sudo] password for yinzhengjie:
[yinzhengjie@s101 data]$
[yinzhengjie@s101 data]$ tail - /etc/profile
#ADD PHOENIX
PHOENIX_HOME=/soft/phoenix
PATH=$PATH:$PHOENIX_HOME/bin
[yinzhengjie@s101 data]$
[yinzhengjie@s101 data]$ source /etc/profile
[yinzhengjie@s101 data]$
5>.将phoenix类库放置在hbase的lib目录，分发，并重启hbase
[yinzhengjie@s101 ~]$ cp /soft/phoenix/phoenix-4.10.-HBase-1.2-client.jar /soft/hbase/lib/
[yinzhengjie@s101 ~]$ xrsync.sh /soft/hbase/lib/phoenix-4.10.-HBase-1.2-client.jar

注意，数据在Phoenix端插入，建议不要在HBase端手动插入，否则会抛出异常：“Error: ERROR 201 (22000): Illegal data. Expected length of at least 4 bytes, but had 2 (state=22000,code=201)”
