             Summary: Revert "HIVE-21685 Wrong simplification in query with 
multiple IN clauses"
                 Key: HIVE-27151
                 URL: https://issues.apache.org/jira/browse/HIVE-27151
             Project: Hive
          Issue Type: Sub-task
            Reporter: Aman Raj
            Assignee: Aman Raj


The multi_in_clause.q fails because Hive is not able to parse 
explain cbo
select * from very_simple_table_for_in_test where name IN('g','r') AND name 
IN('a','b')
If we want this to work, I am able to do it in my local. We have 2 options :
a. Either revert HIVE-21685 since this scenario was not validated back then 
before adding this test.
b. This fix was present in https://issues.apache.org/jira/browse/HIVE-20718 but 
to cherry pick this we need to cherry pick 
https://issues.apache.org/jira/browse/HIVE-17040 since HIVE-20718 has a lot of 
merge conflicts with  HIVE-17040. But after cherry picking these we have other 
failures to fix.
 
I am reverting this ticket for now.
