使用UNION ALL的Hive CTE没有给出正确的结果

Question

WITH suppress AS (
    SELECT
        sdc.nbr,
        sdc.STATUS,
        label,
        type_nm,
        opt_out,
        cust_opt_out,
        subject,
        recordtypeid
    FROM
        sdc
        JOIN return wr ON
            sdc.id = wr.id
    WHERE
        recordtypeid = '0120P0'
    AND STATUS LIKE '%Closed%'
)
SELECT DISTINCT
    suppress.nbr,
    CASE WHEN sp.nbr IS NOT NULL THEN 'Suppressed by Business Rule' ELSE 'Valid for Survey' END AS Case_Suppression,
    sp.Suppression_Rule
FROM
    suppress
    LEFT JOIN (
                  SELECT nbr, 'Fulfillment'      AS Suppression_rule FROM suppress WHERE type_nm = 'Fulfillment'
        UNION ALL SELECT nbr, 'ARS Label'        AS Suppression_rule FROM suppress WHERE cast(label AS INT) >= 1        
        UNION ALL SELECT nbr, 'Business Opt Out' AS Suppression_rule FROM suppress WHERE opt_out = 'true'       
        UNION ALL SELECT nbr, 'Customer Opt Out' AS Suppression_rule FROM suppress WHERE cust_opt_out = 'true'      
        UNION ALL SELECT nbr, 'Basis'            AS Suppression_rule FROM suppress WHERE subject LIKE '%Basis%'     
    ) sp ON suppress.nbr = sp.nbr 

输出：
12456由业务规则履行禁止
被业务规则基础压制的5789
9765适用于Survey NULL

在Impala中返回正确的结果，但是hive没有返回正确的结果。有没有办法在hive中优化查询？
