Hi Guys, I'm writing a UDAF to run against hive 0.5 or hive 0.7. The documentation I can find says to implement UDAFEvaluator and ensure that you implement init() , aggregate() and evaluate(). However, all of the examples I can find implement init(), iterate(), merge(), terminatePartial() and terminate().
What's the difference and where I can find the documentation on how to write a UDAF? Thanks, Pat
