Hello All,

I would request your help on this issue that I am facing. I did see some posts regarding this but none seems to work.

Issue

As we login to Hue, it check configuration and failing with following errors & messages on the screen:

1. Potential misconfiguration detected. Fix and restart Hue.
2. Hive Editor: The application won't work without a running HiveServer2.
3. Impala Editor: No available Impalad to send queries to.

Following are some extracts from hue logs:
