Connection Refused trying to access port 8000 (Hue) into my Hortonworks Sandbox in Azure

[#1]

Hi,

I am trying to access the web UI for Hue, using my Hortonworks Sandbox that is running on Azure.

I am doing a request to -> <myvirtualip>:8000 and having connection refused (ERR_CONNECTION_REFUSED) as answer. However, I can access to Ambari (using <myvirtualip>:8080, built in SSH client (<myvirtualip>:4200), etc.

Please, any help would be very useful.

Thanks in advance!!!

Hi @Santiago Goro

Are you using HDP 2.4?

Can you validate Hue has been started https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.0/bk_installing_manually_book/content/start_h...

Hi Ryan,

Thank you for your answer!

I already started Hue using the commands you sent me. However, when I try to access it through port 8000 I am having NotImplementedError as result.

I am attaching a screenshot notimplementederror.jpg

NotImplementedError at /accounts/login/

Hi @Santiago Goro

After some digging, I found http://gethue.com/how-to-deploy-hue-on-hdp/

It seems the sandbox ships with version 2.6.1 (can you verify you have 2.6.1 by viewing /usr/lib/hue/VERSION)

Can you try to http://gethue.com/hadoop-hue-3-on-hdp-installation-tutorial/

Let me know if that works

What are you trying to do with HUE? You might also consider checking out Ambari Views to see if that could help you accomplish your task.

Hi @Santiago Goro

I took a loot at your server and I found some weird things and fixed them, as described below:

1- When I tried to start hue (service hue start), I receive lots of permissions errors and fixed then changing owner of directory /var/log/hue (chown -R hue:hue /var/log/hue)

2- After turning on debug mode, I saw an error (django.db.utils.DatabaseError: no such table: auth_user), looks like hue database is corrput

3- I started a testserver (/usr/lib/hue/build/env/bin/hue testserver) which creates a fresh database, then I replaced corrupt database with this fresh database (cp /usr/lib/hue/desktop/desktop-test.db /var/lib/hue/desktop.db)

4- Finally, I restarted hue as root: service hue restart.

I'll talk to sandbox team to make sure sandbox 2.4 image from marketplace is ok, it not, we will fix there. if it's ok, we need to find out what cause those weird issues for you.

Thank you Guilherme!!! Amazing news for me. It's working now 🙂

And thank you all guys, for your answers and your time.

I followed this instruction and also did this additional thing to make Hue UI load -> chown -R hue:hue /usr/lib/hue

-Thanks
