Hue standalone connection failure

[ Edited ]

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

 

# Configuration options for Kerberos integration for secured Hadoop clusters
# ------------------------------------------------------------------------
[[kerberos]]

# Kerberos principal name for Hue
hue_principal=hue@MYREALM.COM
# Path to kinit

[hadoop]

# Use WebHdfs/HttpFs as the communication mechanism.
# Domain should be the NameNode or HttpFs host.
# Default port is 14000 for HttpFs.
webhdfs_url=http://master1:50070/webhdfs/v1

# Change this if your HDFS cluster is Kerberos-secured
security_enabled=true
# Configuration for YARN (MR2)
# ------------------------------------------------------------------------
[[yarn_clusters]]

[[[default]]]
# Enter the host on which you are running the ResourceManager
