【中文标题】期望输入“字符串”不匹配：列规范中的“名称”附近

【英文标题】：Mismatched input 'STRING' expecting : near 'name' in column specification

【发布时间】：2014-06-17 02:22:33

【问题描述】：

以下代码出现此错误：

FAILED: Parse Error: line 1:111 mismatched input 'STRING' expecting : near 'name' in column specification

CREATE TABLE country2 
(name string, 
states ARRAY<STRING>,
cities_and_size MAP<STRING, INT>, 
parties STRUCT<name STRING, votes FLOAT, members INT>
)  
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\001'  
COLLECTION ITEMS TERMINATED BY '\002'  
MAP KEYS TERMINATED BY '\003'  
LINES TERMINATED BY '\n'  
STORED AS TextFile;

如果您有任何建议，请提供帮助。 谢谢

【参考方案1】：

对于 STRUCT 类型，字段和数据类型应该用冒号 (:) 分隔。

所以您的查询将如下所示：

CREATE TABLE country2 
(name string, 
states ARRAY<STRING>,
cities_and_size MAP<STRING, INT>, 
parties STRUCT<name:STRING, votes:FLOAT, members:INT>
)  
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\001'  
COLLECTION ITEMS TERMINATED BY '\002'  
MAP KEYS TERMINATED BY '\003'  
LINES TERMINATED BY '\n'  
STORED AS TextFile;

希望这会有所帮助...！！！
