Benjamin Reed commented on PIG-55:
----------------------------------
This looks really good. Let me see if I can get the test cases run against it.
The openDFSFile removal seems unrelated. Correct? Or do you really mean to
remove it?
The other nit I have is that the split returns RecordReader<Text, Tuple>. There
are two issues with this:
1) The first field is not used.
2) RecordReader and Text locks in a dependency on Hadoop. It would be nice if
the split interface could still be valid if Pig was on top of another system.
Iterator<Tuple> seems more general and precise. What do you think? (Granted we
would have to wrap this general iterator into a Hadoop RecordRecord for Hadoop,
but at least it gives a nice interface to the programmer.)

> 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.
