ok. but in my usecase join's/union's wont help. Here is an example of my usecase from postgres, which I have to do it in similar way for hive. with recursive a as (select col from tb1), b as (select col from tb2), c as (select col from tb3)
select a,b,c from a,b,c; which output's me in a dataframe which i am writing to a csv and it looks like a b c 0.1 0.2 0.3 where hive is not supporting `with rec` in same functionality as in postgres and views are also not helping here.
