我正在关注 Michael
当我尝试启动 hadoop **/usr/local/hadoop/bin/start-all.sh**
出现以下错误
mkdir: cannot create directory ‘/usr/local/hadoop/libexec/../logs’: Permission denied
chown: cannot access ‘/usr/local/hadoop/libexec/../logs’: No such file or directory

最佳答案
在那个教程中已经提到了:
Make sure to change the owner of all the files to the hduser user and hadoop group.
请在 hadoop 安装目录中执行以下命令。
例如，如果安装目录是/usr/local/hadoop:
sudo chown -R hduser:hadoop hadoop
关于ubuntu - Ubuntu 上的 Hadoop 启动错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25876691/
