How to implement LEFT/RIGHT OUTER JOIN to replace NOT IN in hive query?

This might help you The query select S.* from empSrc S where S.empid not in (select T.empid from empTrg T) doesn't actually perform a cross join. There is no problem with it.
The same logic can be replicated with not exists
code :
select s.*
from empSrc s 
where not exists (select 1 from empTrg t where t.empid = s.empid)
select s.*
from empSrc s
left join empTrg t on t.empid = s.empid
where t.empid is null --condition to check for non existent records

wish of those help , Your parentheses are not placed right. Try this:
code :
create table db_db.result_av1 as
 select distinct user_name 
 from            movies.user_activity a
 left outer join (select  activity_count as result
                  from    movies.user_activity
                  where   user_activity like "%gz%") d
              on a.user_name=d.user_name
 where a.date between '2015-05-10' and '2015-08-04'
 and   substr(user_name,1,24) is Not null
 limit 5;

I think the issue was by ths following , I have a table otp_data in hive. I take the average of delay based on carrier name, by using below query , You can use something like below
code :
select t2.carrier_desc,  avg(t1.ddelay) 
from otp_data t1 
left outer join carriers t2 
on t1.carrier = t2.carrier
group by t2.carrier_desc;

LEFT OUTER JOIN with DATEDIFF in Hive QL

wish of those help If I understand completely, the result rows will contain a date, the number of installs by unique users on the date, and the count of the number of times the program was executed on the day after an installation across all users.. so, there are 2 different calculations for each date.
My solution starts with a join of the two tables (without the grouping you used) and then subsequent operations use the analytics functions and then group. In my testing, the tables used string types, so dates look like "2013-08-01", etc and DATEDIFF can be used.
