Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/common-services/HUE/4.6.0/package/scripts/hue_server.py", line 76, in <module>
    HueServer().execute()

Change the line 193 below and try to start again.

File:/var/lib/ambari-agent/cache/common-services/HUE/4.6.0/package/scripts/params.py

dfs_namenode_http_address = config['configurations']['hdfs-site']['dfs.namenode.http-address']

to 

dfs_namenode_http_address = 'localhost'

That will give dfs_namenode_http_address a value and get past the error.
