【Hadoop】YARN 完全分布式配置

承接 https://www.cnblogs.com/jzsg/p/12622214.html

mv mapred-site.xml.template  mapred-site.xml

// 基于YARN的资源调度配置
vi etc/hadoop/mapred-site.xml:


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



vi etc/hadoop/yarn-site.xml:


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

    <property>

修改后拷贝至从节点（slave）
scp -r yarn-site.xml root@slave:/usr/local/software/hadoop-2.5.1/etc/hadoop/


$ sbin/start-yarn.sh

$ sbin/stop-yarn.sh


在master上jsp 发现 20906 ResourceManager，从节点发现20808 NodeManager 即成功，
