> Hi, experts:
> Recently, i came across some problems in my hive application, i wondered
> if it is a bug in hive or did some else has the same experience. the problem
> is as follows:
> drop table if exists tb_int;
> create table tb_int(val int);
> insert into tb_int values(1);
> drop table if exists tb_bigint;
> create table tb_bigint(val bigint);
> insert into tb_bigint values(11);
> insert into tb_int select abs(val) from tb_bigint;
> select * from tb_int;
> i expected the result is :
> 1
> 11
> bu , what i actually got is:
> 1
> 0
> I think the result is not reasonable, is it a bug in hive? my hive
> version is 2.3.3， and i tested the 2.3.0 version， the result is the same.
> Could someone give some help, thanks!
