[jira] [Created] (HBASE-9605) Allow AggregationClient to skip specifying column family for row count aggregate

Ted Yu created HBASE-9605:
-----------------------------

             Summary: Allow AggregationClient to skip specifying column family for row count aggregate
                 Key: HBASE-9605
                 URL: https://issues.apache.org/jira/browse/HBASE-9605
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


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.
