at that time. This was tested on 2.4

>          Issue Type: Bug
>    Affects Versions: 2.2.0

> I have noticed where the NN startup did not report any issues the login fails 
> because either the keytab is wrong or the principal does not exist etc. This 
> can be mis leading and lead to authentication failures when a client tries to 
> authenticate to the spnego principal.
