Review comment:
We should check all parts of the hiveHostSplit. So, if hiveHostSplit
(provided via config) is something like x.example.com, we should ensure that
(only) everything below x.example.com (i.e. das.x.example.com) qualifies
instead of checking just the top two levels (which are probably always cloudera
and com at the final DWX deployment).
