Hm, a bunch of UDFs were moved into Pig builtins from piggybank for 0.8. Try
building the piggybank and putting it on your classpath + registering it at
the head of your script.

jar tf pig-0.7.0_9-core.jar | grep builtin
shows over 100 class files like MIN, MAX, SUM, COUNT, etc but no UPPER or
any other string function I want to use. Of course "grep UPPER" shows
nothing.
Which jar file are these string functions supposed to be in?

Try this:
jar tf pig.jar | grep UPPER
to see fi the UDFs are in your jar, and what package they live in.

Thanks.
Somehow, it's not recognizing these functions.

(a-b-c,1)
(x-y,2)
(z,3)

A: {code: chararray,v: int}

The functions need to be part of an expression in a relational operator, for
example -
f = foreach l generate REGEX_EXTRACT_ALL('192.168.1.5:8020', '(.*)\\:(.*)');
(the above example does not make much sense as none of the columns in input
relation are being used.)

I see there are some builtin string functions, but I don't know how to use
them. I got this error when I follow the examples:
grunt> REGEX_EXTRACT_ALL('192.168.1.5:8020', '(.*)\:(.*)');
