Ankur commented on PIG-1273:
----------------------------
Here is a simple script to reproduce it
a = load 'test.dat' using PigStorage() as (nums:chararray);
b = load 'join.dat' using PigStorage('\u0001') as
(number:chararray,text:chararray);
c = filter a by nums == '7';
d = join c by nums LEFT OUTER, b by number USING "skewed";
dump d;
==== test.dat ====
1

===== join.dat =====
1^Aone
2^Atwo
3^Athree
where ^A means Control-A charatcer used as a separator.
