WangMeng updated HIVE-11880:
----------------------------
Description:
For Hive UNION ALL , when an union column is constant(column a such as '0L')
and it has incompatible type with the corresponding column A.
Query with filter condition on type incompatible column a on this UNION ALL
will cause IndexOutOfBoundsException.
Such as TPC-H table "orders", we create View by :
CREATE VIEW `view_orders` AS
SELECT `oo`.`o_orderkey` ,
`oo`.`o_custkey`
FROM (
SELECT `orders`.`o_orderkey` ,
`rcfileorders`.`o_custkey`
FROM `rcfileorders`
UNION ALL
SELECT `orcfileorders`.`o_orderkey` ,
0L AS `o_custkey`
FROM `textfileorders`) `oo`.
In view_orders , 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 'o_custkey' ")
will fail with java.lang.IndexOutOfBoundsException:
'select count(1) from view_orders where o_custkey<100000 '.
