色相安装问题

Question

我是大数据 technologies/hadoop 生态系统的新手。

作为我的一项任务的一部分，我正在尝试在我的单节点 hadoop 集群 [apache distribution hadoop2.6.0] 上安装和 运行 Hue。

我已经按照很多网站提供的说明安装了hue：

1. 已下载最新色调 tar 文件
2. 在一个位置解压
3. 运行 sudo make install
4. 它在 /usr/local/hue 目录中安装了 hue
5. 已更新 hue.ini 文件，其中包含我的集群所需的详细信息。
6. 当我尝试使用“:8888”通过 Web UI 访问新安装的 hue 时，它​​显示以下错误页面：

不知道是什么意思，请帮我解决这个问题

Answer 1

知道了:-)

由于 hue 目录所有权，我遇到了这个问题。

我更改了 /usr/local/hue 文件夹的所有者：

$ sudo chown -R hue:hue /usr/local/hue

然后尝试访问 URL，成功了。 :-)
