[jira] [Updated] (HIVE-25848) Empty result for structs in point lookup optimization with vectorization on

     [ https://issues.apache.org/jira/browse/HIVE-25848?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ádám Szita updated HIVE-25848:
------------------------------
    Description: 
Repro steps:
{code:java}
set hive.fetch.task.conversion=none;

create table test (a string) partitioned by (y string, m string);
insert into test values ('aa', 2022, 1);

select * from test where (y=year(date_sub(current_date,4)) and m=month(date_sub(current_date,4))) or (y=year(date_sub(current_date,10)) and m=month(date_sub(current_date,10)) );

--gives empty result{code}
Turning either of the feature below off yields to good result (1 row expected):
{code:java}
set hive.optimize.point.lookup=false;
set hive.cbo.enable=false;
set hive.vectorized.execution.enabled=false;
{code}
Expected good result is:
{code}
+---------+---------+---------+
| test.a  | test.y  | test.m  |
+---------+---------+---------+
| aa      | 2022    | 1       |
+---------+---------+---------+ {code}
