> 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
