--------------------------------
Summary: LazyBinaryColumnarSerDe: 0 length VARCHAR values are
serialized as NULL
Key: HIVE-13289
URL: https://issues.apache.org/jira/browse/HIVE-13289
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Affects Versions: 0.13.1, 0.12.0, 2.1.0
Reporter: Andy Rosa
On the moment of implementation LazyBinaryColumnarSerDe Hive didn't have the
VARCHAR type implemented. Serializing empty strings is implemented by writing
INVALID_UTF__SINGLE_BYTE
(https://github.com/apache/hive/commit/a266556f2bcf249af110035af1006e52f42046af#diff-aa353060bea2a72013021093b7e8a21cR86).
During the implementation of the VARCHAR type this place was probably missed,
and the VARCHAR type hadn't been added to that IF.
