Description

In LazyHBaseRow，

  private Object uncheckedGetField(int fieldID) {
          // it is a column i.e. a column-family with column-qualifier
          byte [] res = result.getValue(colMap.familyNameBytes, colMap.qualifierNameBytes);

          if (res == null) {
            return null;
          } else {
            ref = new ByteArrayRef();
            ref.setData(res);
          }
      if (ref != null) {
        fields[fieldID].init(ref, 0, ref.getData().length);
      }
  }
  For example, if the fields[fieldID] is Bigint, and ref stores HBase byte data (Long), 
  it will use LazyLong to parse this data and will return NULL value, 
  it should use Bytes.toLong(res.getData()) to parse this byte data
