He Yongqiang updated HIVE-352:
------------------------------
Attachment: hive-352-2009-4-30-4.patch
hive-352-2009-4-30-4.patch does some refactor work to BytesRefArrayWritable.
Maybe the problem is caused by it. I did not see the problem. please make sure
BytesRefArrayWritable can work well since it is a public class. Because many
tests are integrated in TestRCFile and PerformTestRCFileAndSeqFile, so i does
not include seperate tests for BytesRefArrayWritable, ColumnarSerDe. If they
should be provided, i can add them.
Also hive-352-2009-4-30-4.patch added a short cut for creating table with
"STORED AS RCFILE" and includes a test .q file
"columnarserde_create_shortcut.q".

> 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?
