> How to reproduce:
> Input:
> {(a-b,c), (a-b,d)}
> define distinct as DistinctBy('1')
> input = load 'input' as vs:bag{(v0:chararray,v1:chararray)};
> output = foreach input generate distinct(vs);
> dump output;
> expected: {(a-b,c), (a-b,d)}
> actual: {(a-b,c)}
> The bug is caused by the implementation based on splitting the tuple string by '-' to
get tuple parts.
