Hadoop启动dfs权限被拒绝为"hadoop"用户

Question

我在mac local mac上设置了hadoop.当我使用start-dfs.sh命令使用单独的hadoop用户启动-dfs时,我在终端中收到以下错误.

0.0.0.0: mkdir: /usr/local/Cellar/hadoop/2.3.0/libexec/logs: Permission denied

有谁知道如何更改hadoop的日志目录？我用自制软件安装了hadoop.

bash-3.2$ start-dfs.sh

该错误表示权限问题.hadoop用户需要hadoop文件夹的适当权限.尝试在终端中运行以下命令:

sudo chown -R hadoop /usr/local/Cellar/hadoop/2.3.0/
