Hi Team, I recently configured Hue 3.11 with all backend configuration for Hive / WebHDFS etc. However while configuring Spaky/ Livy connectivity on Hue, I am getting 401 unauthorized under "Notebook" section on Hue and also while fetching session data through curl command. Below is the error that I am getting on command line: # curl  http://localhost:8998/sessions <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1" /> Error 401 HTTP ERROR: 401 Problem accessing /sessions. Reason:     Authentication required Powered by Jetty:// Below is the error from Hue: <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1" /> Error 401 HTTP ERROR: 401 Problem accessing /sessions.
