> I want to generate data with bags, so I did this,
> take a simple text file b.txt
> 100          apple
> 200          orange
> 300          pear
> 400          apple
> then run query:
> a = load 'b.txt' as (id, f);
> b = group a by id;
> store b into 'g' using BinStorage();
> then run another query to load data generated from previous step.
> a = load 'g/part*' using BinStorage() as (id, d:bag{t:(v, s)});
> b = foreach a generate (double)id, flatten(d);
> dump b;
> then I got the following result:
> (,100,apple)
> (,100,apple)
> (,200,orange)
> (,200,apple)
> (,300,strawberry)
> (,300,pear)
> (,400,pear)
> the value for id is gone.  If there is no cast, then the result is correct.
