Subject Are there any examples of simple UDAFs?
Date Wed, 08 Dec 2010 05:27:33 GMT
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...
