我的yarn-site.xml文件如下所示（cpu-node0是我的主机名）：

<configuration>
    <property>
            <name>yarn.resourcemanager.hostname</name>
            <value>cpu-node0</value>
    </property>
    <property>
            <name>yarn.nodemanager.aux-services</name>
            <value>mapreduce_shuffle</value>
    </property>
    <property>
            <name>yarn.nodemanager.localizer.address</name>
            <value>${yarn.nodemanager.hostname}:10200</value>
    </property>
    <property>
            <name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
            <value>org.apache.hadoop.mapred.ShuffleHandler</value>
    </property>
    <property>
            <name>yarn.nodemanager.pmem-check-enabled</name>
            <value>false</value>
    </property>
    <property>
            <name>yarn.nodemanager.vmem-check-enabled</name>
            <value>false</value>
    </property>
</configuration>

而且我无法启动从机上的nodemanager，日志文件显示以下错误：

有人能告诉我如何修改文件yarn-site.xml吗？谢谢！
