 === 1. Prepare Kerberos server
 To configure HDFS to use Kerberos you first need to collect information about your Kerberos server, e.g. hostname and port.
 Additionally, you need a service-user which the secret-operator uses to create principals for the HDFS services.
 
 === 2. Create Kerberos SecretClass
