             Summary: Hive SQL using TEZ as execution engine not giving result on empty partition
                 Key: HIVE-25838
                 URL: https://issues.apache.org/jira/browse/HIVE-25838
             Project: Hive
          Issue Type: Bug
    Affects Versions: 3.1.0
            Reporter: dinesh


Hive SQL's on empty partitions giving no result instead of 0 rows or actual value. For example - 

--Create external Table

1) Create external table test_tbl ( name string) partitioned by ( company string, processdate string) stored as orc location '/my/some/random/location';

-- Add partion

2) Alter table test_tbl add partition ( company='aquaifer', processdate='20220101');

 

-- Execute following SQL's which returns no records.

3) select count(*), processdate  from test_tbl  group by processdate  ;

4) select max(processdate ) from test_tbl  ;

 

Same SQL (#3 & #4 above) , when execute with SPARK, returns  '0' count and  '20220101' respectively.
