Subject [jira] Issue Comment Edited: (PIG-157) Add types and rework execution pipeline

-----------------------------------------------------------------------------

This is a core sorts of a patch. I have fixed compile errors so that all the code I have written
till date gets compiled under the current patch. Obviously, there were a lot of dependencies
and I had to resolve them by crude means by commenting out irrelevant but non-compliant functions.
I am hoping that as soon as the logical stuff is done, we should have access to all the data
classes at the least. So the things that are missing/commented are SortedBag and DistinctBag
as they used evalSpecs still. The dependencies on PigContext and backend portion has been
mostly taken care of. I would like the types branch to be updated to this patch asap.

Also attached is a small shell script that I wrote to help me in creating patches. Its not
in perfect shape taking all corner cases into consideration. If used as suggested, it should
be helpful is what I feel. Please take a look and feel free to comment.

> This is the tracking bug for the work to add types to pig and rework the execution pipeline.
 Individual components of this work are covered in subtasks.
> Functional and design specs for this work are:
> http://wiki.apache.org/pig/PigTypesFunctionalSpec
> http://wiki.apache.org/pig/PigTypesDesign
> http://wiki.apache.org/pig/PigExecutionModel
> This work is being done on the branch types, since it is large and disruptive, and we
want to be able to do incremental checkins without causing issues for the trunk.
