Question

我正在尝试将数据加载到我的表中，但发生了一件奇怪的事情：

我创建了我的类型和表格：

create type OfferInfo ( contacted text, channel text, campaign_tp text, hit_home_date timestamp, campaign text, creative text)

create type prdInfo ( PRVCY_CALL int, PRVCY_SWP int, PRVCY_MAIL int, PRVCY_AFIL int, PRVCY_FCRA int, PRVCY_PIPE int, PRVCY_GLBA int);

CREATE TABLE CustPrvcyOffers2 ( ent_cust_id int PRIMARY KEY, prds map<text, frozen<prdInfo>>, offerhist map<text, frozen<OfferInfo>> );

然后我加载这样的数据：

cqlsh:custprod> copy CustPrvcyOffers2 from '/home/ec2-user/part-00000' WITH DELIMITER='|';

50 rows imported in 0.136 seconds.

我做了一个选择*并将其取回：

cqlsh:custprod> select * from CustPrvcyOffers2;

 ent_cust_id | offerhist | prds
-------------+-----------+------

(0 rows)

我怎么没有回来？

另外，我的平面文件如下所示：
