Re: Debugging UDFs

Try to execute in mapreduce mode at least on a pseudo-distributed cluster
and try to find them in specific tasks logs. Also you can try to throw an
exception, just to make sure your code is actually getting there, something
if (true) throw new RuntimeException("My warning");

Best Regards
