--------------------------------------------
Hi [~jerrychenhf] Can you please repeat the test by setting {{hive.vectorized.use.checked.expressions}} to true?

> Key: HIVE-19399
> URL: https://issues.apache.org/jira/browse/HIVE-19399
> Project: Hive
> Issue Type: Bug
> Components: Vectorization
> 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
