Hue standalone connection failure

[#1]

Hi,

I want to make a setup of hue on a separate server which will connect to existing cluster without being a part of  hadoop cluster.

To achive this,i have installed Hue 3.9.0 from CDH package 5.9. After installing hue, i have configured hue.ini to connect to hadoop cluster. Below are the configurations

Hue.ini

# Webserver listens on this address and port

http_host=hueserver1
