Hive进行分区联接

Question

我有这两个表：

table products
(
product_id bigint, 
product_name string
)
partitioned by (product_category as string)

table place_of_sale
(
product_id bigint, 
city string
)
partitioned by (country as string)

我如何基于'product_id'离开2个表，但是将它们放在table_of_sale表的'country'分区上？

我有这两个表：表产品（product_id bigint，product_name字符串）按（product_category作为字符串）分区了表place_of_sale（product_id bigint，city字符串）按（...）分区了...

如果销售的产品是表place_of_sale中存在的产品，则使用LEFT JOIN：

select s.country, p.product_id, p.product_name, p.category, 
       case when s.product_id is NULL then "not sold" else "sold" as sold 
 from products p
      left join place_of_sale s on p.product_id = s.product_id 
 order by country, product_id --order if necessary
