I am trying to write a very simple aggregation function which seems like an overkill for using GenericUDAF as described on the wiki. However, I can't get the code to run. It always throws an exception of the form
java.lang.ClassNotFoundException: com.hadoopbook.hive.Maximum$MaximumIntUDAFEvaluator (As you can see, even the sample code from Tom White's Hadoop book -- the only sample code I found -- doesn't work.) I'm using the standard add jar and create temporary function statements... --Leo
