{noformat}
drop table array_valued_src;
create table array_valued_src (key string, value array<string>);
insert overwrite table array_valued_src select key, array(value) from src;
select sum(val) from (select a.key as key, b.value as array_val from src a join
array_valued_src b on a.key=b.key) i lateral view explode (array_val) c as val;
