yarn-site.xml：

    <property>
        <name>yarn.nodemanager.resource.memory-mb</name>
        <value>106496</value>
    </property>
    <property>
        <name>yarn.scheduler.maximum-allocation-mb</name>
        <value>106496</value>
    </property>

修改后重启yarn

yarn.scheduler.maximum-allocation-mb 参数的作用：该参数在yarn-site.xml配置文件中配置，设置yarn容器的最大分配内存，以MB为单位，如果yarn资源管理器（RM/ResourceManager）中的容器请求的资源大于此处设置的值，就会抛出无效资源请求异常（InvalidResourceRequestException）。
　　yarn.nodemanager.resource.memory-mb参数的作用：该参数在yarn-site.xml配置文件中配置，设置yarn节点上可用的物理内存，默认大小为8192（MB），该内存可用于分配给yarn容器。
