3minutes26seconds.
My tables are stored as orc and
u still have available space. This also

Hi all,
Is there a way in hive that different tables data, can be read as in a
single query?
example:
(something like)
select a,b from (select col1 from tbl1)a , (select col1 from tb2)b);
output as :
a b
0.1 0.2
Any help is appreciated.
Thanks
