>    Affects Versions: 3.1.0
>            Reporter: Haifeng Chen
>            Priority: Major
>
>  The following sql scripts generating different result for vectorization disabled and
enabled (both for ORC and for parquet).
>    drop table test_schema;
>    create table test_schema (f int) stored as parquet;
>    insert into test_schema values ('99999');
>    select cast(f as tinyint) + 1 from test_schema;
> For non-vectorization, the result is -96 while for vectorization mode, it is 100000
