> The RowCounter use FirstKeyOnlyFilter regardless of whether or not the
> command line argument specified a column family (or family:qualifier).
> In case when no qualifier was specified as argument, the scan will
> give correct result. However in the other case the scan instance may
> have been set with columns other than the very first column in the
> row, causing scan to get nothing as the FirstKeyOnlyFilter removes
> everything else.
