binlijin commented on HIVE-3868:
--------------------------------
The reason is：
We use HBase's Bytes to convert long and other data type to byte data and store
in hbase.
Then use hive to analysis the data in hbase.
> Use Hive‘s serde to parse HBase’s byte Data in LazyHBaseRow

> Key: HIVE-3868
> URL: https://issues.apache.org/jira/browse/HIVE-3868
> Project: Hive
> Issue Type: Bug
> Components: HBase Handler
> Affects Versions: 0.9.0
> Reporter: binlijin
>
> 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}
