>
> For Hive UNION ALL , when a union column is constant(column a such as
> '0L') and it has incompatible type with the corresponding column A. The
> query with filter condition on type incompatible column a on this UNION-ALL
> results will cause IndexOutOfBoundsException
> Such as TPC-H table "orders", we CREATE VIEW `view_orders` AS select
> `oo`.`o_orderkey` , `oo`.`o_custkey` from ( select `orders`.`o_orderkey` ,
> `rcfileorders`.`o_custkey` from `tpch270g`.`rcfileorders` union all select
> `orcfileorders`.`o_orderkey` , 0L as `o_custkey` from
> `tpch270g`.`textfileorders`) `oo`.
> Type of 'o_custkey' is INT normally, while the type of corresponding
> column constant "0" is BIGINT.
> Then the fllowing query(with filter incompatible column 0_custkey) will
> fail with java.lang.IndexOutOfBoundsException:
> 'select count(1) from view_orders where o_custkey<100000 '.
