我收到这个错误。
我读过很多人得到这个错误，但我一直没能找到解决方案。任何人都可以帮忙??

解决方案

创建一个单独的用户 - hduser ，总是推荐

   -  do chown -R 755 / usr / local / hadoop 
  - 创建类似/ app的tmp路径时/ hadoop / tmp，应用与上面相同的设置
  

希望这可以解决问题。 p>

问题与权限有关，而不是hadoop

I am getting this error. I have read that many people get this error but I have not beeen able to find a solution for this. Can anyone help??

解决方案

make a separate user - hduser, always recommened

- do chown -R 755 /usr/local/hadoop
- when creating tmp paths like /app/hadoop/tmp, apply the same settings as above

Hopefully, this will resolve the issue.

The issue is related to permission, not hadoop
