Hive 避免蜂巢中的自连接

我正在使用蜂箱内置的collect_set功能。该表如下所示：

 cookie, events, keywords,pages 
 1234      1      'dress'  10
 1234      1      'dress'  10
 1235      2      'shoes'  14
 1234      5      'socks'  22

使用collect_set，我可以得到以下结构

   select cookie, collect_set(events) as ev, collect_set(keywords) as kwords, 
   collect_set(pages)
    from table1 
    group by cookie

我需要做的是搜索收集的数组，多次，例如：

 select cookie 
 ,array_contains(collect_set(events),2) as has_2
 ,array_contains(collect_set(keywords),1) as has_4
  from table1
  group by cookie) A 

据我所知，我无法将一个字段投影超过1次，最终不得不执行以下操作

 select a.cookie,a.has_2,b.has_4 from ( 
 select cookie 
 ,array_contains(collect_set(events),2) as has_2 
 from table1 group by cookie ) A
 inner join 
 select cookie 
 ,array_contains(collect_set(events),4) as has_4
 from table1 group by cookie) B 
on A.cookie = B. cookie

最终结果如下：

 cookie, has_2, has_4 
 1234     F      F 
 1235     T      T 

在没有自联接的情况下，有什么方法可以做到这一点吗？目前，我必须自我加入大约30次，以获得我需要的格式

谢谢

您应该在SQL中引入一个GROUP BY

e、 g

-将groupby添加到示例中

select
    cookie,
    array_contains(collect_set(events),2) as has_2,
    array_contains(collect_set(keywords),1) as has_4
 from
    table1
 group by
    cookie;

select S.cookie, array_contains(S.events_set,2), array_contains(S.events_set,4) 
from
(select cookie, collect_set(events) as events_set
 from table1 group by cookie ) S
