1、服务器环境

<table> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:85.2pt;"> 主机名 </td> 
 <td style="vertical-align:top;width:85.2pt;"> Ip </td> 
 <td style="vertical-align:top;width:85.2pt;"> 用户名 </td> 
 <td style="vertical-align:top;width:85.25pt;"> 密码 </td> 
 <td style="vertical-align:top;width:85.25pt;"> 安装目录 </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:85.2pt;"> master </td> 
 <td style="vertical-align:top;width:85.2pt;"> 192.168.199.131 </td> 
 <td style="vertical-align:top;width:85.2pt;"> root </td> 
 <td style="vertical-align:top;width:85.25pt;"> 123456 </td> 
 <td style="vertical-align:top;width:85.25pt;"> /usr/softwares </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:85.2pt;"> slave1 </td> 
 <td style="vertical-align:top;width:85.2pt;"> 192.168.199.132 </td> 
 <td style="vertical-align:top;width:85.2pt;"> root </td> 
 <td style="vertical-align:top;width:85.25pt;"> 123456 </td> 
 <td style="vertical-align:top;width:85.25pt;"> /usr/softwares </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:85.2pt;"> slave2 </td> 
 <td style="vertical-align:top;width:85.2pt;"> 192.168.199.134 </td> 
 <td style="vertical-align:top;width:85.2pt;"> root </td> 
 <td style="vertical-align:top;width:85.25pt;"> 123456 </td> 
 <td style="vertical-align:top;width:85.25pt;"> /usr/softwares </td> 
 </tr> 
 </tbody> 
</table>

2、集群规划

<table> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> Master </td> 
 <td style="vertical-align:top;width:142.05pt;"> Slave1 </td> 
 <td style="vertical-align:top;width:142.05pt;"> Slave2 </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> Namenode </td> 
 <td style="vertical-align:top;width:142.05pt;"> Namenode </td> 
 <td style="vertical-align:top;width:142.05pt;"> &nbsp; </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> Datanode </td> 
 <td style="vertical-align:top;width:142.05pt;"> Datanode </td> 
 <td style="vertical-align:top;width:142.05pt;"> Datanode </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> Zookeeper </td> 
 <td style="vertical-align:top;width:142.05pt;"> Zookeeper </td> 
 <td style="vertical-align:top;width:142.05pt;"> Zookeeper </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> ResourceManager </td> 
 <td style="vertical-align:top;width:142.05pt;"> ResourceManager </td> 
 <td style="vertical-align:top;width:142.05pt;"> ResourceManager </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> NodeManager </td> 
 <td style="vertical-align:top;width:142.05pt;"> NodeManager </td> 
 <td style="vertical-align:top;width:142.05pt;"> NodeManager </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> HMaster </td> 
 <td style="vertical-align:top;width:142.05pt;"> HMaster </td> 
 <td style="vertical-align:top;width:142.05pt;"> Hmaster </td> 
 </tr> 
 <tr> 
 <td style="vertical-align:top;width:142pt;"> RegionServer </td> 
 <td style="vertical-align:top;width:142.05pt;"> RegionServer </td> 
 <td style="vertical-align:top;width:142.05pt;"> RegionServer </td> 
 </tr> 
 </tbody> 
</table>

3、采用的组件版本如下：

Ubuntu16.04;hadoop-2.7.3;jdk1.8.0\_191;zookeeper-3.4.11;hbase-1.4.9-src.tar.gz
