Hi Jamie, I am also working on a UDF that has to take 2 arguments. Hive detects the number of arguments you declare in your evaluate method automatically it seems so you can work with multiple arguments.
So far so good, but after that I have some problems that the 2nd argument (String in my case) does not seem to be passed on to the evaluate method in the right format during job execution.
