django - 色调安装问题

Question

我是大数据技术/hadoop 生态系统的新手。

作为我的一项作业的一部分，我尝试在我的单节点 hadoop 集群 [apache distribution hadoop2.6.0] 上安装并运行 Hue。

我已经按照许多网站提供的说明安装了hue:

1. 下载最新的hue tar文件
2. 将其解压缩到一个位置
3. 运行sudo make install
4. 它在/usr/local/hue目录中安装了hue
5. 更新了hue.ini 文件，其中包含集群所需的详细信息。
6. 当我尝试使用“:8888”通过 Web UI 访问新安装的色调时，它向我显示以下错误页面:

不知道这是什么意思，请帮我解决这个问题

问候，布佩什

Answer 1

明白了:-)

由于hue目录所有权的原因，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

然后尝试访问该 URL，成功了。 :-)
