英文:

Could not run jar file in hadoop3.1.3

问题

我在命令提示符（以管理员身份运行）中尝试了以下命令：
```plaintext
hadoop jar C:\Users\tejashri\Desktop\Hadoopproject\WordCount.jar  WordcountDemo.WordCount  /work /out

但是我收到了以下错误消息：
我的应用程序被停止了。

"'C:\Program Files\Java\jdk1.8.0_171'" is not recognized as an internal or external command,
operable program or batch file."

The `JAVA_HOME` variable is not properly set in `hadoop-env.cmd`.

Also, move the JDK installation to a folder without whitespaces (say, `C:\Java\jdk1.8.0_171`)

Update the `JAVA_HOME` and `PATH` environment variables

Add this line in `hadoop-env.cmd`,

set JAVA_HOME=C:\Java\jdk1.8.0_171

Restart the hadoop daemons and run the Job.
