-------------------------------------
Ashutosh,
First, the changes are not going to be in framework till Hadoop 22 and I don't
think we want to wait that far as we are seeing quite a few problems on our
cluster. Second, I think we want to take a direction with pig of setting things
up for users. Of course, we don't have stats right now to do so accurately but
I think this is a step in the right direction

> 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.
