> For rowcounter job, column family is not required as input parameter.
> AggregationClient requires the specification of one column family:
> {code}
>     } else if (scan.getFamilyMap().size() != 1) {
>       throw new IOException("There must be only one family.");
>     }
> {code}
> We should relax the above requirement for row count aggregate where FirstKeyOnlyFilter would be automatically applied.
