------------------------------

    Attachment: hive-352-2009-4-30-3.patch

Sorry for the wrong file attached earlier. 
hive-352-2009-4-30-3.patch can be compiled with hadoop-0.17.0. hive-352-2009-4-30-3.patch
use vint for some fields of key part. I tested with vint and int, and can not see their differences
in my test.

> column based storage has been proven a better storage layout for OLAP. 
> Hive does a great job on raw row oriented storage. In this issue, we will enhance hive
to support column based storage. 
> Acctually we have done some work on column based storage on top of hdfs, i think it will
need some review and refactoring to port it to Hive.
> Any thoughts?
