-- union query without UDF
explain
select * from (select key + key from src limit 1) a
union all
select * from (select key + key from src limit 1) b;
add jar /tmp/udf-2.2.0-snapshot.jar;
create temporary function myudf as
'com.aginity.amp.hive.udf.UniqueNumberGenerator';
-- Now try the query with the UDF
explain
