Subject [jira] Updated: (HIVE-133) Add support for RecordIO in serde2
Date Thu, 17 Dec 2009 23:58:18 GMT


Namit Jain updated HIVE-133:

    Fix Version/s:     (was: 0.5.0)

> Add support for RecordIO in serde2
> ----------------------------------
>                 Key: HIVE-133
>                 URL:
>             Project: Hadoop Hive
>          Issue Type: Improvement
>          Components: Serializers/Deserializers
>            Reporter: Johan Oskarsson
> 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
