bzip2 compression

Hi,

I have a requirement to implement Parquet with bzip2 compression because it's splitable. Right now, we can't provide bzip2 in PIG.

SET parquet.compression none/gzip/SNAPPY;

Is there any way to compress to bzip2 on top parquet ?

No files or tests are named. Start by tracing the existing parquet.compression setting and how PIG passes codec choices; then determine the integration needed for bzip2. Done means bzip2 is accepted alongside none, gzip, and SNAPPY and works for the requested PIG use case.
