------------------------------
Attachment: hive-352-2009-4-15.patch
This is the latest work on this issue.
1) added new columnar serde
2) new columnar struct
3) RCFile now includes a partial read test
4) RCFileOutputFormat now implements HiveOutputForamt
I think next step, more tests are needed, especaill on HiveOutputFormat.

> 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?
