**[Hadoop 2.7.4 + HBase 1.2.6 + ZooKeeper 3.4.10 配置][Hadoop 2.7.4 _ HBase 1.2.6 _ ZooKeeper 3.4.10]**

本文为上述配置的一部分，为方便阅读，故设为独立页面

参考：[http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/ResourceManagerHA.html][http_hadoop.apache.org_docs_current_hadoop-yarn_hadoop-yarn-site_ResourceManagerHA.html]

**1：配置**

首先创建local临时目录：/home/mytestzk/hadoop-2.7.4/tmp/yarn

*  yarn-site.xml

**特别注意：**对以下节点yarn.resourcemanager.ha.id，需要在每个ResourceManager上修改对应的值，但在其它机器上不需要此节点，比如在master机器上设置为rm1， 在slave1机器上设置为rm2

**2：启动YARN**

正常启动HDFS后，因为配置了master及slave

为ResourceManager，所以需要分别在master 及 slave1上执行命令（注：需要在每个ResourceManager上执行启动命令）:

sbin/start-yarn.sh

**3：查看状态：**

从命令行查看状态：bin/yarn rmadmin -getServiceState rm1

![1222875-20171226160505541-655877443.png][]

或在浏览器中查看：master:8088, 及slave1:8088

**4： 验证HA**

将active的resourcemanager 进程杀掉 kill -9 \{进程id\}，然后再查看yarn状态变化，可以原来的standby将变为active

**5：HDFS HA** **及YARN HA** **命令总结**

<table style="width:687px;"> 
 <tbody> 
 <tr> 
 <td> 　 </td> 
 <td> 在每个zookeeper server </td> 
 <td> HDFS HA 在任一个NameNode </td> 
 <td> YARN HA 在每个ResourceManager </td> 
 </tr> 
 <tr> 
 <td> 启动 </td> 
 <td> bin/zkServer.sh start </td>
