Hue隧道访问失效

发表于 | 更新于 | 分类于 ，

判断应该是Django框架中,发送报文的MIME有问题
path地址

HUE通过隧道访问

HUE通过隧道映射到本地后发现所有的JavaScript文件解析有问题:

Refused to execute script from 'http://127.0.0.1:18888/static/desktop/js/jquery.tablescroller.038d8a8feae9.js' because its MIME type ('text/x-js') is not executable, and strict MIME type checking is enabled.

问题在于cloudera中Django的配置文件具体在哪,后来终于终于找到了

HUE文件路径:
