Opened https://github.com/cloudera/hue/issues/968

From https://github.com/cloudera/hue/issues/968 it seems that the fix will not be in either CDH 5.x or 6.x, but in a new CDP platform (hortonworks + cloudera). This is interesting since we were planning to move to CDH6, but not sure for how long it will be supported then.

So, it seems Hue doesn't run in python3.
What's the next step here?

Grosking: We can try to see if it works with CDH5,
or we could deprecate Hue, and use sth else?

I'd be personally in favor of deprecating (in the long term) Hue, in theory we should be able to use notebooks for hive queries and the Airflow dashboard for the rest (speculations of course, we'll need to test).

I tested today building Hue 4.7.1 on a Buster VM, using python3.7 as target, and Hue seems to start fine (the development server at least). Given T258768 I'd be inclined to see if we can package Hue's builds into a Debian package, and test it on our environment. We'd still have the plan to get rid of Hue asap, but we'd be able to move to Buster and python3 in the meantime (deprecating Oozie is still a long road).

After some battling with Debian packages, I created https://github.com/cloudera/hue/issues/1239 since it is not clear to me what is the best build procedure.
