Hi,
I'm trying to do a pretty simple regex test in PIG right now and getting
a weird error. All I'm doing is:

orig_set = load '/data/dictionaries/Eng-Spa.dic' USING PigStorage('\t')
AS (orig: CHARARRAY, trans: CHARARRAY);
filtered = FILTER orig_set BY REGEX_EXTRACT(orig, '^[\\#\\<]') == 1;

The error I get is:
2012-02-16 12:45:24,000 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1045: Could not infer the matching function for
org.apache.pig.builtin.REGEX_EXTRACT as multiple or none of them fit.
Please use an explicit cast

Ideas?

Cheers,
Eli

Can you try with RegexMatch? I am doing something similar in one of my
scripts and it works fine.

Cool, actually, I just got what I wanted to work like this:

filtered = FILTER orig_set BY orig MATCHES  '^[\\#\\<].*';

I didn't know MATCHES worked for regex before. Sweet!
