> Create a KerberosHelper method to create the headless Kerberos identities and
> keytab files (inline).
> This can be used to create the common identities and keytab files before
> parallel invocations attempt to do so. Due to a race condition, parallel
> invocations of the server-side actions to create principals and keytab files
> may lead to invalid keytab files being distributed to some host because the
> password contained in them were clobbered.
> By calling this new method before calls to install and start services the
> potential of the race condition will be avoided.
> {code}
> boolean ensureHeadlessIdentities(Cluster cluster, Map<String, Map<String,
> String>> existingConfigurations, Set<String> services)
> throws KerberosInvalidConfigurationException, AmbariException;
> {code}
