> Adding new datanode to Ozone on a secured cluster with kerberos and TLS. 
> Datanode failed to start after assigning Ozone datanode role. In particular 
> if entries of kdc and admin_server in krb5.conf contains old value point to 
> some other random host. The old value was not updated to reflect the newly 
> assigned Ozone DN role in the new cluster.
> The result was DN failed to start. The expectation is corresponding entries 
> in krb5.conf on these nodes got updated when assigned DN role for Ozone.
