How to resolve Error 401 Authentication required in HUe?

[#1]

Hello,

I've enabled kerberos on my cluster and i've installed on it Hue. Hue was running correctly until kerberos is enabled.

I've configured kerberos for Hue by following this link:

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.2/bk_security/content/kerb-config-hue.html

When i accessed to my Hue UI and i navigate through it to Pig, Hive ... I got the errors mentioned in "error1.png" and "error2.png".

How can i fix this issue?

To validate the hue kerberos ticket as hue user run.What the output of the below statement?

$ klist 

Forcefully expire the ticket

$kdestroy 

As hue user grab a Kerberos ticket

$ kinit -k -t /etc/security/keytabs/hue.service.keytab hue/$FQDN@REALM 

Validate by running

$klist 

Retry the earlier steps

Hello, the output of $klist as hue user is:

Ticket cache: FILE:/tmp/krb5cc_1019
Default principal: hue/ambari@ROSAFI.COM
Valid starting Expires Service principal
11/13/17 14:17:25 11/14/17 00:17:25 krbtgt/ROSAFI.COM@ROSAFI.COM
renew until 11/20/17 14:17:25

I've tried to grab a kerberos ticket as mentioned above but i still get the same error when i access to my Hue UI.

@Geoffrey Shelton Okot

I've already checked it and made the necessary configurations to configure Hue with kerberos but i still get the same errors. I'm really stuck. How can i let hue authenticate with my components cluster?

@raouia

Let me quickly reproduce your environment,

HDP cluster 2.6.3 Kerberized?
Hue version and OS link you used for download and installation?

Can you briefly describe your environment?

[#7]

@Geoffrey Shelton Okot

Sorry for the delay.

HDP cluster is 2.6.1 and is kerberized. I've also install on it Ranger and Ranger KMS.

My Os is Ubuntu 14.04.
