> The UDF RegexMatcher, reports its progress using the reporter (PigProgressable) object in the exec method. It seems that the reporter object is not being set in the EvalFunc and hence the following piece of Pig script runs into problems in the mapper with the following error.
> {code}
> register string.jar;
> define getCompanyName string.RegexMatcher('www.(.*).com');
> a = load '/user/viraj/myurldata.txt' as (url:chararray, count:long);
> b = foreach a generate url, getCompanyName(url) as bcookie;
> dump b;
> {code}
