Hmm, this is an interesting case. I think there may be a bug here.
grunt> grouped = load 'thing' as
(seedword:chararray,baggy:{outertup:(groupy:(seedword:chararray,
coword:chararray))});
grunt> describe grouped;
grouped: {seedword: chararray,baggy: {groupy: (seedword: chararray,coword:
chararray)}}
notice that outertup has been thrown out. I suppose having a bunch of
nested tuples is equivalent to getting rid of them, still, it's not
something that pig should do. For the Pig devs, is this expected?
Either way. in this case, you would do:
a = foreach grouped generate seedword, baggy.coword;
and go for there
let me know if that works
