> {{CqlInputFormat.describeSplits}} handles the case of no entry in the 'system.size_estimates'
table but does not handle the situation when there is a zero size estimate in the table. This
can happen if an input job is started immediately after data is added but before the {{SizeEstimatesRecorder}}
has run.
> {{CqlInputFormat.describeSplits}} should handle 0 size estimate in the same manner as
no size estimate and not sub-split but return the full split.
