binlijin updated HIVE-3868:
---------------------------
Description:
In LazyHBaseRow，
{code}
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
{code}
