>            Reporter: Eugene Chekanskiy

>
> When starting Ambari where Kerberos authentication is enabled 
> (authentication.kerberos.enabled=true), Ambari validates the relevant 
> configuration properties. If a sever issue is found, an exception is thrown. 
> This causes issues in installations where Ambari is expected to be able to 
> perform Kerberos authentication but all of the data is available for since 
> this is it expected to be provided later. For example, the SPNEGO keytab file 
> will be created when Kerberos is enabled sometime after Ambari starts up.
> To prevent Ambari from shutting down when all the required data is not 
> available, thrown exceptions should be removed from 
> org.apache.ambari.server.configuration.Configuration#createKerberosAuthenticationProperties.
