Failed to create principal - hadoop@domain - can not check if principal exists

[#1]

I am trying to ENABLE Kerberos. I entered KDC configs and then Kadmin_host, admin_principal and admin_password.

Then it is successfully installing Kerberos cliend but failing while testing Kerberos client with below error:

Failed to create principal - hadoop@domain - can not check if principal exists

-> I find this error in "ambari-audit.log"

I have a container in my Active Directory called KnoxUsers and I have "knxadmin" as user.

I have put 'knxadmin' as Admin_Principal while configuring Kerberos.

Can anyone points me where I need to check to correct this error?

Brief Description about my cluster:

I have single node cluster which I deployed using ambari on a VM on a host-machine. I have active directory setup on a domain controller. My domain controller and host-machine are on the same domain.
