1. I want to test logic of my UDF without running the whole pig. I can set breakpoints, e.t.c. 2. UDF accepts a bag of tuples. I have source data which I want to read using AvroStorage to tuples and feed to UDF. Avro storage would preserve schema. I don;t have to wrie cusotm converters/cast'ers e,t,c,
>>Or you can extract the >>logic to a java method outside of the UDF and test it within normal junit Who will convert sample avro data for me to Tuples and feed them to java method? I don't want to invent the wheel and repeat AvroStorage functionality. 2013/8/30 Ruslan Al-Fakikh <metarus...@gmail.com> > Hi, > > What exactly do you want to test? The logic inside UDFs?
