hadoop - 非字符串值在 Hive 中显示为 NULL

Question

我是 HIVE 的新手，正在创建我的第一张桌子！

由于某种原因，所有非字符串值都显示为 NULL（包括 int、BOOLEAN 等）

我的数据看起来像这个示例行：

58;"management";"married";"tertiary";"no";2143;"yes";"no";"unknown";5;"may";261;1;-1;0;"unknown";"no"

我用它来创建表：

create external table bank_dataset(
age       TINYINT, 
job       string, 
education string, 
default   BOOLEAN, 
balance   INT, 
housing   BOOLEAN, 
loan      BOOLEAN, 
contact   STRING,
day       STRING, 
month     STRING, 
duration  INT,
campaign  INT, 
pdays     INT, 
previous  INT,
poutcome  STRING,
y         BOOLEAN)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\u003B'
STORED AS TEXTFILE
location '/user/marchenrisaad_gmail/Bank_Project'
tblproperties("skip.header.line.count"="1");

感谢评论它的工作！但我有 1 个问题。对于每一行，我都正确获取了所有数据，然后我得到了额外的空值列。在我的代码下面找到：

create external table bank_dataset(age TINYINT, job string, education string, default BOOLEAN, balance INT, housing BOOLEAN, loan BOOLEAN, contact STRING,day INT, month STRING, duration INT,campaign INT, pdays INT, previous INT, poutcome STRING,y BOOLEAN)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
WITH SERDEPROPERTIES (
   "separatorChar" = "\u003B",
   "quoteChar"     = '"'
)  
STORED AS TEXTFILE
location '/user/marchenrisaad_gmail/Bank_Project'
tblproperties("skip.header.line.count"="1");

有什么建议么？
