> gives wrong results 0 than expected results.
> STEPS TO REPRODUCE:
> create table s1(id smallint) stored as orc;
> insert into table s1 values (1000),(1001),(1002),(1003),(1000);
> set hive.vectorized.execution.enabled=true;
> select count(1) from s1 where cast(id as char(4))='1000';
> – this gives 0
> set hive.vectorized.execution.enabled=false;
> select count(1) from s1 where cast(id as char(4))='1000';
> – this gives 2
