Adding Impala to HUE

[#1]

I added Impala as a service after the installation of CDH6 

Impala via commandline on the box works but it doesn't work in HUE

I followed the instructions  per the documents and 

and from here 

https://community.cloudera.com/t5/Web-UI-Hue-Beeswax/Do-not-see-impala-app-in-hue-after-installation...

According to @Romainr I need to add  the following to the HUE.ini

    [[[impala]]]
      name=Impala
      interface=hiveserver2

 Every time I add something to 

Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini

and try to restart the service the service refuses to start

am I not putting the condition in the right place or in the right format?

It suppose to be a simple change from None to Impala and it should work

I had to customize

Hue Server Advanced Configuration Snippet (Safety Valve) for hue_safety_valve_server.ini

to add back the base functionality
