create table status_updates(userid int,status string,ds string);
create table profiles(userid int,school string,gender int);
drop table school_summary; create table school_summary(school string,cnt int) partitioned
by (ds string);
drop table gender_summary; create table gender_summary(gender int,cnt int) partitioned by
(ds string);

insert into status_updates values (1, "status_1", "2016-03-16");
insert into profiles values (1, "school_1", 0);

set hive.auto.convert.join=false;
set hive.execution.engine=spark;

FROM (SELECT a.status, b.school, b.gender
FROM status_updates a JOIN profiles b
ON (a.userid = b.userid and
a.ds='2009-03-20' )
) subq1
INSERT OVERWRITE TABLE gender_summary
PARTITION(ds='2009-03-20')
SELECT subq1.gender, COUNT(1) GROUP BY subq1.gender
INSERT OVERWRITE TABLE school_summary
PARTITION(ds='2009-03-20')
SELECT subq1.school, COUNT(1) GROUP BY subq1.school
