You can download the release candidate for 0.8 from http://people.apache.org/~olga/pig-0.8.0-candidate-0
. If you want to build your own I'd build off the 0.8 branch, which
we know to be stable. We're pouring all kinds of cool new features
into trunk at the moment so it may not be as stable as you'd want
right at the moment.

I can use new code, yes. If I simply use the dev version of pig,
will it
support this then?

Actually, in 0.8 the code you give will work, if you cast
min_generated to
an int. 0.8 Is in the release process now. Are you in a position
to use
new code?

something more clever that can be done, although I think it points
to a
bigger question.
Basically, let's say I have (whatever:chararray, icare:int)
I want to get whatever, icare/min(all_of_icare), for each touple.
Basically
something akin to...
loaded = LOAD 'whatever' AS (whatever:chararray, icare:int)
min_generated = FOREACH loaded GENERATE icare;
min_group = GROUP min_generated ALL;
min = FOREACH min_group GENERATE MIN(min_generated);
generated = FOREACH loaded GENERATE whatever, icare/***min***;
obviously this code would not work, but I am wondering if
something in the
spirit of it can be done in Pig.
Thank you for your time
