Configuring Hue to use a dedicated Impala coordinator

If you have separate Impala executors and coordinators on your CDP cluster, then you can configure Hue to use a dedicated Impala coordinator for running queries.

  1. Log into Cloudera Manager as an Administrator.
  2. Go to Clusters > Hue > Configuration > Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini and add the following lines under the [impala] section:
    	# URL of the Impala coordinator server
  3. Click Save Changes.
  4. Restart the Hue service.
Hue uses the dedicated Impala coordinator server to execute queries.
