Hadoop 无法创建配置单元表

我无法创建配置单元表。 下面是代码

CREATE TABLE NYSE(exchange STRING, stock_symbol STRING, stock_date DATE,
stock_price_open FLOAT, stock_price_high FLOAT, stock_price_low FLOAT,     
stock_price_close FLOAT, stock_volume INT, stock_price_avg_close FLOAT)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ','; 

这将返回以下错误消息：

NoViableAltException(332@[2189:1: columnNameTypeOrPKOrFK : ( ( foreignKeyWithName ) | ( primaryKeyWithName ) | ( primaryKeyWithoutName ) | ( foreignKeyWithoutName ) | ( columnNameType ) );])

我正在使用Hive2.1.0和Hadoop2.7.3

请帮助我。

您不能在列名定义中使用“exchange”

尝试像exchange_1一样给出，或者使用`对您的第一个列名进行转义

尝试以下步骤：

USE your_DB_Name;

DROP TABLE IF EXISTS NYSE PURGE;

CREATE TABLE NYSE (`exchange` STRING, stock_symbol STRING, stock_date DATE, stock_price_open FLOAT, stock_price_high FLOAT, stock_price_low FLOAT, stock_price_close FLOAT, stock_volume INT, stock_price_avg_close FLOAT) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' ;

是配置单元中的保留关键字

可以使用反勾（``）符号对其进行转义

这应该起作用：

CREATE TABLE NYSE(
`exchange` STRING
,stock_symbol STRING
,stock_date DATE
,stock_price_open FLOAT
,stock_price_high FLOAT
,stock_price_low FLOAT
,stock_price_close FLOAT
,stock_volume INT
,stock_price_avg_close FLOAT)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';

exchange是配置单元中的关键字，因此无法使用。而不是使用exchangee或其他任何东西。 试试这个

创建表nyse（交换对象字符串、股票符号字符串、股票日期 字符串，股票价格开双，股票价格高双，股票价格低 双倍，股价双倍，成交量双倍 double，stock_price_adj_close double）行格式分隔字段 以“，”终止
