Subject [jira] Updated: (PIG-55) Allow user control over split creation
Date Mon, 10 Mar 2008 23:42:50 GMT

Charlie Groves updated PIG-55:
------------------------------

    Attachment: pig_chunker_split_v2.patch

Looks like I uploaded an earlier version of the patch without Javadoc.  This version removes
some superfluous cleanup I did and adds Javadoc for Chunk and Chunker.  I still need to go
back and add some unit tests for Chunk and Chunker though.

> I have a dataset in HDFS that's stored in a file per column that I'd like to access from
pig.  This means I can't use LoadFunc to get at the data as it only allows the loader access
to a single input stream at a time.  To handle this usage, I've broken the existing split
creation code out into a few classes and interfaces, and allowed user specified load functions
to be used in place of the existing code.
