Description

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.
