Mixing
HUE Query Left Join no Results
I run a hivesql in Hue 3.10.0 and return no results, Hive SQL like this:
select t1.id
,t2.id
from (
select id from table1 where date = '20181121' and type = 'a'
) t1
left join(
select id from table1 where date = '20181121' and type = 'b' and
) t2
on t1.id = t2.id;
Then I run sunquery t1:
select id from table1 where date = '20181121' and type = 'a';
and it retrun 437 rows,
I try add "group by" after subquery t1,and query like this:
select t1.id
,t2.id
from (
select id from table1 where date = '20181121' and type = 'a' group by id
) t1
left join(
select id from table1 where date = '20181121' and type = 'b' and
) t2
on t1.id = t2.id;
it also returns 437 rows;
Then I change table1 to another table, which return a normal result, I use another tool "superset" to run the first query above, it also returns 437 rows, So I doubt "Hue" caused this problem, But I am puzzled why it happened?
