>    For UNION ALL , when an union operator is constant column (such as '0L', BIGINT Type)
 and its corresponding column has incompatible type (such as INT type). 
>   Query with filter condition on type incompatible column on this UNION ALL  will cause
IndexOutOfBoundsException.
>  Such as TPC-H table "orders",in  the following query:
>  Type of 'orders'.'o_custkey' is INT normally,  while  the type of corresponding constant
column  "0" is BIGINT( `0L AS `o_custkey` ). 
>  This following query (with filter "type incompatible column 'o_custkey' ")  will fail
 with  java.lang.IndexOutOfBoundsException : 
> {code}
> set hive.cbo.enable=false;
> set hive.ppd.remove.duplicatefilters=true;
> CREATE TABLE `orders`(
>   `o_orderkey` int, 
>   `o_custkey` int, 
>   `o_orderstatus` string, 
>   `o_totalprice` double, 
>   `o_orderdate` string, 
>   `o_orderpriority` string, 
>   `o_clerk` string, 
>   `o_shippriority` int, 
>   `o_comment` string);
> SELECT o_orderkey
> FROM   (
>               SELECT `o_orderkey` ,
>                      `o_custkey`
>               FROM   `orders`
>               UNION ALL
>               SELECT `o_orderkey`,
>                      0L  AS `o_custkey`
>               FROM   `orders`) `oo`
> WHERE  o_custkey<10;
> {code}
