Phoenix 实现 SQL On HBase
友情提示：Ubuntu 14.04 下，HBase 单机伪分布式部署，不使用 HBase 自带的 Zookeeper
目录
- 下载 Phoenix
- 配置
- 启动
- 命令行测试
HBase 是基于 Hadoop 的分布式数据库，既然是数据库，增删改查是必备功能。但不知是何缘故，HBase 提供了一套自己的查询语言（HBase shell 常用命令），而不是类SQL。这无形中增加了 HBase 的使用成本。那么问题来了，可否使用 类SQL 语句操作 HBase 呢？
下载 Phoenix
Phoenix Downloads
去上述链接下载特定的版本，笔者选择的是 apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz 和 apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz.md5 。
校验下载的压缩文件
blockchain@Dao:~/Downloads$
blockchain@Dao:~/Downloads$ md5sum apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz
82996e0b3979e57a46e25e3c36a2ee98 apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz
blockchain@Dao:~/Downloads$
blockchain@Dao:~/Downloads$ cat apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz.md5
82996e0b3979e57a46e25e3c36a2ee98 *apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz
校验通过。解压该压缩文件，
blockchain@Dao:~/Downloads$ tar -zxvf apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz -C ~
配置
- 将 phoenix-4.14.0-HBase-1.4-client.jar 和 phoenix-core-4.14.0-HBase-1.4.jar 两个jar包拷贝至Hbase的 lib 文件夹
blockchain@Dao:~/apache-phoenix-4.14.0-HBase-1.4$ cp phoenix-4.14.0-HBase-1.4-client.jar ~/hbase-1.4.6/lib/
blockchain@Dao:~/apache-phoenix-4.14.0-HBase-1.4$
blockchain@Dao:~/apache-phoenix-4.14.0-HBase-1.4$ cp phoenix-core-4.14.0-HBase-1.4.jar ~/hbase-1.4.6/lib/
blockchain@Dao:~/apache-phoenix-4.14.0-HBase-1.4$
- 将Hbase的配置文件 hbase-site.xml 拷贝至 Phoenix根目录中的 bin 文件夹
blockchain@Dao:~/hbase-1.4.6$
blockchain@Dao:~/hbase-1.4.6$ cp conf/hbase-site.xml ~/apache-phoenix-4.14.0-HBase-1.4/bin/
blockchain@Dao:~/hbase-1.4.6$
至此，配置完成。
启动
- 启动HDFS
- 启动YARN
- 启动HBase
- 启动Phoenix
