The trunk patch was integrated 3 weeks ago.
Maybe open a new JIRA for the backport ?

> 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.
