Subject [jira] Commented: (PIG-1249) Safe-guards against misconfigured Pig scripts without PARALLEL keyword

Olga Natkovich commented on PIG-1249:
-------------------------------------

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.
