集羣部署模型 

修改配置文件

[root@node01 hadoop]# cp mapred-site.xml.template mapred-site.xml
[root@node01 hadoop]# vi mapred-site.xml


 <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
  </property>

[root@node01 hadoop]# vi yarn-site.xml


 <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>

<property>
   <name>yarn.resourcemanager.ha.enabled</name>
   <value>true</value>
 </property>
 <property>
   <name>yarn.resourcemanager.cluster-id</name>
   <value>cluster1</value>
 </property>
 <property>
   <name>yarn.resourcemanager.ha.rm-ids</name>
   <value>rm1,rm2</value>
 </property>
 <property>
   <name>yarn.resourcemanager.hostname.rm1</name>
   <value>node03</value>
 </property>
 <property>
   <name>yarn.resourcemanager.hostname.rm2</name>
   <value>node04</value>
 </property>
 <property>
   <name>yarn.resourcemanager.zk-address</name>
   <value>node02:2181,node03:2181,node04:2181</value>
 </property>

分發配置文件

[root@node01 hadoop]# scp mapred-site.xml yarn-site.xml node02:/opt/hadoop/hadoop-2.6.5/etc/hadoop/

[root@node01 hadoop]# scp mapred-site.xml yarn-site.xml node03:/opt/hadoop/hadoop-2.6.5/etc/hadoop/

[root@node01 hadoop]# scp mapred-site.xml yarn-site.xml node04:/opt/hadoop/hadoop-2.6.5/etc/hadoop/
 

開啓yarn集羣

[root@node01 hadoop]# start-yarn.sh

在node03,node04開啓resourcemanager

[root@node03 ~]# yarn-daemon.sh start resourcemanager
[root@node04 ~]# yarn-daemon.sh start resourcemanager

訪問WEB端口

 重定向node03

查看node04的狀態信息
