             Summary: Const struct equality operator throws error when CBO is 
off and vectorization is on
                 Key: HIVE-26550
                 URL: https://issues.apache.org/jira/browse/HIVE-26550

Repro:
{code:java}
set hive.fetch.task.conversion=none;
set hive.cbo.enable=false;

create table test (a string) partitioned by (y string, m string);
insert into test values ('aa', 2022, 9);

select * from test where (struct(2022) = struct(2022));{code}
Result:
