Enabling multiple editors in Hue

Hue now no longer displays all available interpreters by default. If you prefer to display all available interpreters in the UI, you can explicitly enable them using a configuration flag.

Log in to Cloudera Manager as an Administrator.
Go to Cloudera Manager > Clusters > Hue > Configuration.
Search for the Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini.
Add the following flag to enable displaying all interpreters in the Hue navigation pane:
```
[notebook]
enable_all_interpreters=true
```

(Optionally) Explicitly configure interpreters by adding entries under the [[interpreters]] section:

[notebook]
[[interpreters]]
[[[<interpreter_name>]]]
name=[***display_name***]
interface=[***interface_type***]

Click Save Changes.
Restart the Hue service.
