将数据加载到Hive的struct数组

Question

我的CSV数据看起来像

David,"""SMARTPHONE,6""|""COMPUTER,3""|""LAPTOP,1"""

我尝试将其加载到配置单元表中

create table user_device(name string, devices array<struct<devicename: string, number : int>>) 
FIELDS TERMINATED BY ','
collection items terminated by '|'
STORED AS TEXTFILE
LOCATION 'maprfs:///user/david/';

我希望看到

[{"devicename":"SMARTPHONE","number":6},{"devicename":"COMPUTER","number":3},{"devicename":"LAPTOP","number":1}]

但是当我尝试查询表时，我看到struct的数组是

[{"devicename":"\"\"\"SMARTPHONE","number":null}]

数组和结构的其余部分都消失了。

有人知道我能做到这一点吗？

谢谢 大卫
