Add support for RecordIO in serde2
----------------------------------
Key: HIVE-133
URL: https://issues.apache.org/jira/browse/HIVE-133
Project: Hadoop Hive
Issue Type: Improvement
Affects Versions: 0.19.0
Reporter: Johan Oskarsson
Fix For: 0.19.0
Currently there is no support for Hadoop's RecordIO (also known as Jute) in
Hive's new serde version 2.
I believe quite a few Hadoop installations are using SequenceFiles with keys
and values in a combination of normal Writables and generated RecordIO classes.
This issue needs to cover the following points (as suggested by Joydeep Sen
Sarma):
- traditionally our serde's have ignored the keys altogether (the row is
embedded in the value).
- the jute code was written for an older version of the serde interface and
needs to be ported to the new interface
