Eli Reisman commented on HIVE-3264:
-----------------------------------
Looking at the source, I'm seeing AvroSerDe code mapping BYTE to
Constants.TINYINT_TYPE_NAME in Hive, but binary type (array/blob) already maps
to Constants.BINARY_TYPE_NAME -- and inside the Hive constants, I see no "byte"
type to replace TINYINT_TYPE_NAME, is there something I'm missing? I could not
tell from the description whether the binary type is what you were discussing
(looks like its already in place), or the single-byte type in specific. In that
case, there is no replacement I can find for tiny int on the Hive side. I
didn't see anything on the binary array being implemented as tiny ints any more
in the code. I am looking in the org.apache.hive.serde2.* packages.

> When the AvroSerde was written, Hive didn't have a binary type, so Avro's
> byte array type is converted an array of small ints. Now that HIVE-2380 is
> in, this step isn't necessary and we can convert both Avro's bytes type and
> probably fixed type to Hive's binary type.
