我正在尝试使用以下代码在配置单元中创建动态分区。

SET hive.exec.dynamic.partition = true;
SET hive.exec.dynamic.partition.mode = nonstrict;

create external table if not exists report_ipsummary_hourwise(
ip_address string,imp_date string,imp_hour bigint,geo_country string)
PARTITIONED BY (imp_date_P string,imp_hour_P string,geo_coutry_P string) 
row format delimited 
fields terminated by '\t'
stored as textfile
location 's3://abc';

insert overwrite table report_ipsummary_hourwise PARTITION (imp_date_P,imp_hour_P,geo_country_P)
SELECT ip_address,imp_date,imp_hour,geo_country,
       imp_date as imp_date_P,
       imp_hour as imp_hour_P,
       geo_country as geo_country_P
FROM report_ipsummary_hourwise_Temp;

其中report_ipsummary_hourwise_Temp表包含以下列，ip_address，imp_date，imp_hour和geo_country
我收到此错误
语义异常错误分区规范{imp_hour_p=空，imp_date_p=空，geo_country_p=空}包含非分区列。
有谁能告诉我为什么会出现这种错误吗？
