binlijin updated HIVE-3868:
---------------------------

    Description:=20
In LazyHBaseRow=EF=BC=8C
{code}
  private Object uncheckedGetField(int fieldID) {
          // it is a column i.e. a column-family with column-qualifier
          byte [] res =3D result.getValue(colMap.familyNameBytes, colMap.qu=
alifierNameBytes);

          if (res =3D=3D null) {
            return null;
          } else {
            ref =3D new ByteArrayRef();
            ref.setData(res);
          }
      if (ref !=3D null) {
        fields[fieldID].init(ref, 0, ref.getData().length);
      }
  }
  For example, if the fields[fieldID] is Bigint, and ref stores HBase byte =
data (Long),=20
  it will use LazyLong to parse this data and will return NULL value,=20
  it should use Bytes.toLong(res.getData()) to parse this byte data
{code}

  was:
In LazyHBaseRow=EF=BC=8C
{code}
  private Object uncheckedGetField(int fieldID) {
          // it is a column i.e. a column-family with column-qualifier
          byte [] res =3D result.getValue(colMap.familyNameBytes, colMap.qu=
alifierNameBytes);

          if (res =3D=3D null) {
            return null;
          } else {
            ref =3D new ByteArrayRef();
            ref.setData(res);
          }
      if (ref !=3D 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 v=
alue, it should use Bytes.toLong(res.getData()) to parse this byte data
