How about the pig jar lib path? Sometime after building my UDF, I register the new udf jar, but I had forgot the old udf jar remain in the $PIG_HOME/lib/, and when the pig code used the UDF class, and it will use the classes compiled in the old udf rather than the new one. Maybe your troublesome is related this?
