Hi Jeff,
Thanks for the quick response. I will review and commit the patch. I am going
to add a log statement for the reduce value that has been computed. I will also
copy your doc comment from the src to the JIRA to assist our doc writer

> It would be *very* useful for Pig to have safe-guards against naive scripts
> which process a *lot* of data without the use of PARALLEL keyword.
> We've seen a fair number of instances where naive users process huge
> data-sets (>10TB) with badly mis-configured #reduces e.g. 1 reduce.
