pig hangs on the last line on the script below when I run with -x local. It runs fine when
run on hadoop.
Happy to provide the files used in bugrep.pig below: v2.txt and document-date.pl (michaelniv@gmail.com)
I initially ran into a problem which involved cogrouping two things like id_docdate_s1 below,
but this is what I came up with while tightening down my bugreport.
Thanks in advance.

-- bugrep.pig

DEFINE get_doc_date `document-date.pl`;

id_text1 = LOAD 'v2.txt' AS (id,text);
id_docdate1 = STREAM id_text1 THROUGH  get_doc_date AS (id,docdate);
id_docdate_s1 = ORDER id_docdate1 BY docdate;
store id_docdate_s1 into 'f1.out';

id_text2 = LOAD 'v2.txt' AS (id,text);
id_docdate2 = STREAM id_text2 THROUGH  get_doc_date AS (id,docdate);
id_docdate_s2 = ORDER id_docdate2 BY docdate;
store id_docdate_s2 into 'f2.out';    -- second store call hangs pig
