Russell, fire that neurologist who didn't care about what you had to think about your own problems!! ;-)
But honestly though, I use booleans in my pig scripts too. The trouble is that you can store a boolean into a row (awkwardly by returning from UDF: "t=foreach u generate IsEmpty(u.bag) as bool_var;" ), but you can't actually use a boolean column. T = filter t by bool_var; There are oppositions to writing scripts using this, the argument is that wtf bother with this boolean column? The more natural thing in Pig would be to split on that boolean column and then use the two aliases separately. Personally, to me, having boolean column makes it easier to think about... Anyways, where have you (guys all) use booleans in pig?
