做一个单独的用户 - hduser，总是推荐

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

希望这将解决问题。

问题与权限有关，与 hadoop 无关

以下是 2 条非常有用的建议：

  1. 最好检查一下 .bashrc 文件中是否设置了 HADOOP_HOME 和 JAVA_HOME。有时，不设置这些环境变量也可能在启动 hadoop 集群时导致错误。

  2. 通过查看 /usr/local/hadoop/logs 目录中生成的日志文件来调试错误也很有用。
