Zhichun Wu updated HIVE-5067:
-----------------------------
Attachment: HIVE-5067.patch
I would like to test orc + bzip2 for cold data compression and have a quick imp
with BZip2Compressor in [apache common
compress|http://commons.apache.org/proper/commons-compress/] based on
SnappyCodec.java . Right now I just implement the CompressionCodec interface
only.
According to my test, orc + bzip2 doesn't have significant improvement on data
compression compared to orc + zlib and it takes more time to complete the
compression. Please correct me if I'm wrong.

> It would be good to add a bzip compressor for ORC. Bzip does very well for
> long term/cold storage.
