Sorry, my question had a 2 part. Sorry I did not make that clear. Setting up different kdcs as suggested above works for configuration and HA. However, the user wants to configure a kdc with a load balancer to ease up the traffic. if 2 kdcs are setup, then users can still connect to the heavy used one instead of being redirected to the idle one via loadbalancer. Does this make sense?

Thanks for the reply all. This was a non issue. Ambari is reading JMX and JMX is incorrectly aggregating GC Times. Similar to: https://issues.apache.org/jira/browse/AMBARI-3178 Thanks for the help

Yes but it varies heavily depending the day/time. At times, it could be intensive. I am not sure it is heavy at this moment but let me get that

While trying to configure kdc with a Virtual IP, we are getting the below error Could not find user in Kerberos database Ambari fails the install. VIP is needed for loadbalancing and HA. When single node IP is used for kdc, then the install is successful.
