WangMeng updated HIVE-11880:
----------------------------
Description:
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 '.
