+The kerberos.removeHostFromPrincipal and the kerberos.removeRealmFromPrincipal properties are used to normalize the user principal name before comparing an identity to acls
+applied on a Znode. By default the full principal is used however setting the removeHostFromPrincipal and removeRealmFromPrincipal kerberos properties to true will instruct
+Zookeeper to remove the host and the realm from the logged in user's identity for comparison. In cases where NiFi nodes (within the same cluster) use principals that
+have different host(s)/realm(s) values, these kerberos properties can be configured to ensure that the nodes' identity will be normalized and that the nodes will have
+appropriate access to shared Znodes in Zookeeper.

The last line is optional but specifies that clients MUST use Kerberos to communicate with our ZooKeeper instance.
Now, we can start NiFi, and the embedded ZooKeeper server will use Kerberos as the authentication mechanism.
