Hi,
Pig seems not to handle backslashes at the end of string literals properly.
I've tried several variations and haven't gotten it to work. Backslashes inside
of string literals still work fine. Can someone confirm this, or what the
correct syntax would be for a string literal ending in a backslash?

a = load 'test1.txt' using PigStorage(',') as
(A:chararray,B:chararray,C:chararray);
dump a;
b = foreach a generate 'abcd\\\\abcd';
dump b;
c = foreach a generate 'abcd\\\\';
dump c;
