------------------------------------

             Summary:  Query performs extremely slow with hive.vectorized.adaptor.usage.mode = chosen
                 Key: HIVE-25242
                 URL: https://issues.apache.org/jira/browse/HIVE-25242
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
    Affects Versions: 4.0.0
         Environment: If hive.vectorized.adaptor.usage.mode is set to chosen only certain UDFS are vectorized through the vectorized adaptor.

Queries like this one, performs very slowly because the concat is not chosen to be vectorized.

select count(*) from tbl where to_date(concat(year, '-', month, '-', day)) between to_date('2018-12-01') and to_date('2021-03-01');  {code}
            Reporter: Attila Magyar
             Fix For: 4.0.0
