Hbase tables not loading in Hue

[daveliu864]

Hi guys,

I have built Hue 4.10 in a Docker container and I am trying to connect to Hbase within my cluster through the Hue browser, however most of the Hbase tables that I try to load on Hue end up with this error:

During handling of the above exception, another exception occurred:

The Docker image was built instead of pulled as our cluster uses Kerberos and we had to add krb5-config and krb5-user libraries to the Dockerfile. We were also having errors with Gunicorn before which cause Hue to not load up at all, resulting in just a white page. This was fixed by modifiy the hue.ini file so gunicorn_work_class=gthread instead of eventlet. I am wondering if these two fixes have somehow cause the current Hbase issue.

Just wondering if anyone else if having this problem and if there are ways to fix it?
