我有以下一组配置单元表：

create table image_additions (
    customer_id STRING,
    image_key STRING,
    image_size STRING
);
create table image_removals (
   customer_id STRING,
   image_key STRING,
   image_size STRING
);
create table images_stored (
   customer_id STRING,
   image_key STRING,
   image_size STRING
);

我想从如下查询中运行insert：

insert into images_stored
select ia.customer_id, 
       ia.image_key, 
       ia.image_size 
from image_additions ia 
where ia.image_key not in 
       (select ir.image_key from image_removals ir);

这会产生笛卡尔积，而hive不允许我运行它。如何使用另一个查询来实现这一点？
