Is it possible to define our own comparator class for using order by in pig?

I want to order the tuples 开发者_Go百科using my own comparator class. If I run a query like say " B = ORDER A by $0,$1 " Then the ordering should be done based on my comparator. Please reply... Thanks

This used to be possible, but was taken out due to the fact that a) no one used it and b) it added a lot of unnecessary complexity to the code.

If you have a compelling use case, please shoot an email to the Pig user list.
