1.配置 mapred-site.xml(集群所有文件)
进入目录 /usr/local/hadoop/etc/hadoop/

vim /usr/local/hadoop/etc/hadoop/mapred-site.xml
写入
<property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>

2.配置yarn-site.xml(集群所有文件)
进入目录 /usr/local/hadoop/etc/hadoop/

vim /usr/local/hadoop/etc/hadoop/yarn-site.xml
写入
<property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
</property>
<property>
 <name>yarn.nodemanager.auxservices.mapreduce.shuffle.class</name>    <value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
<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>slave2</value>
</property>
<property>
   <name>yarn.resourcemanager.hostname.rm2</name>
   <value>slave3</value>
</property>
<property>
   <name>yarn.resourcemanager.zk-address</name>
   <value>slave1:2181,slave2:2181,slave3:2181</value>
 </property>

3.yarn启动
master上执行 start-all.sh
此时nodemanager和resourcemanager不会启动,需要在master上:

yarn-daemon.sh start nodemanager     

在slaveX上:

yarn-daemon.sh start resourcemanager     

运行JPS发现master上有nodemanager,slaveX上有resourcemanager。则yarn启动完成。
