Can I manage separate clusters of HDP and HDF with single Kerberos KDC server?

I have independent clusters of HDF and HDP. I wonder if I can have a single KDC Admin server for both of the clusters.

If it is possible, how do I achieve that.

Make sure your realm name is all uppercase characters. hdfs-hadoopprod@Hortonworks.com should really be hdfs-hadoopprod@HORTONWORKS.COM.

Also, the default settings are for the headless/user principal names to include the cluster name. If you choose to stay with this, make sure the clusters have unique names. However, you are welcome to change the unique value for these principal names to anything that avoids a collisions. If principals names are the same in multiple Ambari-managed clusters using the same KDC, one instance of Ambari will wind up changing the passwords out from under the other other instances. This will invalidate the keytab files installed on the hosts and break the clusters.
