Hue standalone connection failure

Contributor

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
http_port=8162
# This should be the Hue admin and proxy user
default_user=hdfs
