我是窗口用户。这是我的yarn-site.xml配置，还有一件事是，在手动运行这个项目之前，我只启动data node和name node，而不是通过start-all.cmd命令。还有什么我必须启动的吗？只是我的想法，比如资源经理之类的。
yarn-site.xml文件

<configuration>

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

生成此错误是因为您的用户名有一个空格，因此在您的目录中出现%20。
为了解决这个问题，我们执行以下步骤：
打开命令提示符（win键+r->键入“cmd”->单击“run”）
输入netplwiz
选择帐户并单击“属性”按钮
输入帐户的新名称（不带空格）
在此步骤旁边，可能会出现以下问题：有0个datanode正在运行，并且此操作中没有排除任何节点
但在windows中，您可以通过以下方式解决此问题：
删除c:\hadoop-2.8.0\data\datanode\current中的版本文件
重新启动hadoop。
删除输出目录：

hdfs dfs -rm -r /path/to/directory

好好享受。
