pig 0.8.1 - Iterating contents of a Bag
Hello there,
I am loading a data in form of

A1: {key: chararray,keywords: {keywords_tuple: (keyword: chararray)}}

I believe the Sample data would look like the following

{1, {('amit'),('yahoo'),('pig')}

I am trying to write a foreach where I can loop through the each keyword in the bag.

I tried writing this but it seems to not dump the output the way I want to see
    GENERATE keywords.keyword;

I would like to see


Instead it prints the entire bag at once like the one below.


Please note I do not want to flatten the bag as what I want to process each keyword in the bag using a UDF later on.

Appreciate any of your inputs.
