（1）进入文件夹

[hadoop@hadoop000 hadoop]$ pwd
/home/hadoop/app/hadoop-2.6.0-cdh5.15.1/etc/hadoop

（2）复制文件，更名为mapred-site.xml

[hadoop@hadoop000 hadoop]$ cp mapred-site.xml.template mapred-site.xml

（3）配置mapred-site.xml

[hadoop@hadoop000 hadoop]$ vi mapred-site.xml

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

（4）配置yarn-site.xml

[hadoop@hadoop000 hadoop]$ vi yarn-site.xml

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

（5）启动

[hadoop@hadoop000 sbin]$ ./start-yarn.sh

（6）此时启动中的状态

[hadoop@hadoop000 sbin]$ jps
2976 DataNode
3552 NodeManager
3173 SecondaryNameNode
3429 ResourceManager
3879 Jps
2827 NameNode

（7）访问YARN浏览器界面
