Olga Natkovich resolved PIG-683.
--------------------------------
Resolution: Invalid
We can't change semantics of an existing functions. If users need a different
interface, they can create another function that suits their needs
> Semantics of TOKENIZE are not clear
> -----------------------------------

> Key: PIG-683
> URL: https://issues.apache.org/jira/browse/PIG-683
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: types_branch
> Reporter: Santhosh Srinivasan
> Fix For: types_branch
>
>
> The semantics of TOKENIZE are not clear. In its current form, TOKENIZE takes
> as input a string and returns a bag. The bag contains 1 tuple per token. The
> tuple in turn contains a single token. A better approach would be to return a
> tuple (instead of a bag) that contains as many elements as there are tokens.
> On a secondary note, the outputSchema method in TOKENIZE is broken. It should
> return a bag with a tuple that contains a string and not just a string.
