Question

我正在关注Michael

当我尝试启动hadoop **/usr/local/hadoop/bin/start-all.sh**

时

我收到以下错误

mkdir: cannot create directory ‘/usr/local/hadoop/libexec/../logs’: Permission denied

在该教程中已经提到过：

确保将所有文件的所有者更改为hduser用户和hadoop组。

请在hadoop安装目录中触发以下命令。例如，如果安装目录为/usr/local/hadoop：

sudo chown -R hduser:hadoop hadoop

Ubuntu上的Hadoop启动错误
