"hadoop"用户的 Hadoop 启动 dfs 权限被拒绝

Question

我在 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，我在终端中收到以下错误。

0.0.0.0: mkdir:/usr/local/Cellar/hadoop/2.3.0/libexec/logs: 权限被拒绝

有谁知道如何更改 hadoop 的日志目录？我使用 Homebrew 软件安装了 hadoop。

bash-3.2$ start-dfs.sh

该错误表明存在权限问题。 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/
