Hive 否定<=&燃气轮机&引用；蜂箱操作员工作不正常？

我必须在这里添加一些介绍，因为这么说我的问题主要是代码；）

这是我的测试：

CREATE TABLE test (
  c1 string,
  c2 string
);

INSERT INTO test VALUES
  (NULL, NULL),
  ('A', NULL),
  ('A', 'B'),
  ('A', 'A')
;

SELECT *, (c1 <=> c2) as is_equal, (NOT (c1 <=> c2)) as is_not_equal
FROM test;

我希望：

test.c1,test.c2,is_equal,is_not_equal
NULL,NULL,true,false
A,NULL,false,true
A,B,false,true
A,A,true,false

这是蜂房里的虫子吗

此查询按预期工作：

SELECT *,
(c1 is null and c2 is null) or (c1 is not null and c2 is not null and c1 = c2) as is_equal,
(NOT ((c1 is null and c2 is null) or (c1 is not null and c2 is not null and c1 = c2))) as is_not_equal
FROM test;

我们使用Hive 1.2.1（来自HDP2.6.2）

我无法重现此问题并获得预期结果。您正在使用哪个版本的Hive？我们使用Hive 1.2.1（来自HDP2.6.2）

SELECT *,
(c1 is null and c2 is null) or (c1 is not null and c2 is not null and c1 = c2) as is_equal,
(NOT ((c1 is null and c2 is null) or (c1 is not null and c2 is not null and c1 = c2))) as is_not_equal
FROM test;
