    Description: 
This unit test fails:

    byte [] fam2 = Bytes.toBytes("columnB");
    initHRegion(tableName, getName(), fam1, fam2);

    byte [] rowA = Bytes.toBytes("rowA");
    byte [] rowB = Bytes.toBytes("rowB");

    byte [] value = Bytes.toBytes("value");

    Delete delete = new Delete(rowA);
    delete.deleteFamily(fam1);

    region.delete(delete, null, true);

    // now create data.
    Put put = new Put(rowA);
    put.add(fam2, null, value);
    region.put(put);

    put = new Put(rowB);
    put.add(fam1, null, value);
    put.add(fam2, null, value);
    region.put(put);

    Scan scan = new Scan();
    scan.addFamily(fam1).addFamily(fam2);
    InternalScanner s = region.getScanner(scan);
    List<KeyValue> results = new ArrayList<KeyValue>();
    s.next(results);
    assertTrue(Bytes.equals(rowA, results.get(0).getRow()));

    results.clear();
    s.next(results);
    assertTrue(Bytes.equals(rowB, results.get(0).getRow()));

  }
