Iterating over contents of a tuple.

[Parth Sawant]

Hi
I'm trying to run Pig's REPLACE UDF over all the fields in every tuple in a
Pig relation.
The REPLACE UDF does not however work with the * operator to run itself
over the contents of each field in a tuple.
For eg:

SRC= LOAD 'input' using PigStorage('\\u001') as
(col1:chararray,col2:chararray,col3:chararray,col4:chararray);

REP=FOREACH SRC GENERATE REPLACE(col1,'str1','str2');

I want to iterate this same replace function over all the columns in a
tuple.

Any help appreciated.

Thanks
