“的Hadoop启动dfs权限被拒绝”；hadoop“；用户

我已经在mac本地mac上安装了hadoop。当我使用单独的hadoop用户使用

start dfs.sh

命令启动dfs时，我在终端中得到以下错误

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

有人知道我如何更改hadoop的日志目录吗？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用户需要对hadoop文件夹具有适当的权限。尝试在终端中运行以下命令：

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

您提到您正在使用一个单独的

hadoop

用户。您是否尝试将hadoop文件夹的所有权更改为user

hadoop

？
