我指的是{{3>} hadoop-1.1.1安装。
我的所有文件和权限都是根据此链接设置的。 但是我收到了这个错误。请帮忙。

由于错误表明您遇到了权限问题。 您需要为hduser提供适当的权限。尝试：
sudo chown -R hduser /usr/local/hadoop/

运行此命令以更改hadoop目录的权限
sudo chmod 750 / app / hadoop

以下是2条非常有用的建议：
最好检查是否设置了HADOOP_HOME和JAVA_HOME .bashrc文件。有时，不设置这些环境变量 启动hadoop集群时也可能导致错误。
通过浏览/ usr / local / hadoop / logs目录中生成的日志文件来调试错误也很有用。
