--------------------------------------------

+1

nit: I'd reverse the order of the comparison to avoid a double negative (!= .. else)

> On upgrading to 2.2+, if the new {{role_manager}} option is not added to {{cassandra.yaml}},
an instance of the default {{CassandraRoleManager}} is created during initialization of {{DatabaseDescriptor}}.
This is a problem as the set of role options supported by {{CRM}} depends on the configured
{{IAuthenticator}}, which at that point in time is always {{AllowAllAuthenticator}}.
> This StackOverflow post describes the problem; the configured authenticator is {{PasswordAuthenticator}},
the role manager should allow roles to be created using the {{PASSWORD}} option, but it does
not.

> The simple workaround is to ensure that yaml contains the role manager option
> {code}
> role_manager: CassandraRoleManager
> {code}
