Cheolsoo Park updated PIG-3015:
-------------------------------
Attachment: PIG-3015-22June2013.diff
I updated the patch again hoping that this will be committed -
PIG-3015-22June2013.diff.
The patch that Joe uploaded (PIG-3015-20May2013.diff) was missing a couple of
test files and included few unnecessary changes. I added missing files and
cleaned up the patch a bit. The unit tests pass in Hadoop 20 and 23.
AFAICT, most comments in the jira have been incorporated, so I think we should
commit this patch. I am maintaining the code in my private repo at work now,
but I'd love to see this going in...

> The current AvroStorage implementation has a lot of issues: it requires old
> versions of Avro, it copies data much more than needed, and it's verbose and
> complicated. (One pet peeve of mine is that old versions of Avro don't
> support Snappy compression.)
> I rewrote AvroStorage from scratch to fix these issues. In early tests, the
> new implementation is significantly faster, and the code is a lot simpler.
> Rewriting AvroStorage also enabled me to implement support for Trevni (as
> TrevniStorage).
> I'm opening this ticket to facilitate discussion while I figure out the best
> way to contribute the changes back to Apache.
