HIVE HA : automatic failover

I have installed HUE 4.6.0 and configured it to work with HIVE HA
If an HiveServer2 instance failed while HUE is connected, I can see that the connection is cut.
Is there a automatic failover handled by HUE in order to reconnect to the available HiveServer2 instances using Zookeeper ?

AFAIK there is a feature about this but I did not test it yet.

I don’t find this feature in
Where is it explained ?
