Hive 配置单元表输出在查询时显示一个不存在的空值

我知道有人问过类似的问题，但我对配置单元表的Select查询返回了所有正确的列和一个额外的NULL列

我已经创建了一个配置单元表，现在尝试使用SELECT查询它

DDL：

表DDL：

CREATE TABLE IF NOT EXISTS family (name STRING COMMENT 'Member Name', 
Age INT COMMENT 'Age of the Member', 
floor INT COMMENT 'Residence floor', 
salary float COMMENT 'per month salary', 
birthplace STRING COMMENT 'State of birth', 
education STRING, 
gender STRING )
COMMENT 'basic details of fmaily members'
LOCATION " /user/hive/warehouse/family/MANJREKAR"
TBLPROPERTIES ('creator'='Sarang', 'created_at'='2019-10-06 14:00:00') ;

DML：

从家庭中选择姓名、薪资

输出：

如何仅获取查询所选的列？

整个行都会显示在名称字段中。所有其他字段均为空

由于这是第一个字段，我打赌文件中的分隔符不是代码中指定的分隔符

---

您似乎有逗号分隔的数据，这不是配置单元表的默认值

在这里查看一个关于声明表的正确语法的示例：

它将整行放在name字段中。所有其他字段均为空
