Kerberos is recommended, but not required.

@eorgad If you do not have Kerberos enabled on the cluster, then Kerberos is not required.

On other note, If your cluster is already Kerberized, then yes, Kerberos is required for adding Ranger KMS service as well. So, if you add Ranger KMS service using Ambari on already Kerberized cluster, Ambari will automatically Kerberize Ranger KMS as well depending on if you used Ambari to manage Kerberos for cluster using KDC Admin credential. Else, ensure to create principle and keytabs for Ranger KMS service as well.
