可以使用dinamic分区设置下一个参数。

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

下面是一个代码示例：

create table temp.accounts           (                                                                                                                                                                                     
first_name                  string
,last_name                  string
,zipcode                  string
)
partitioned by (areacode string)
stored as parquet location '/temp.db/accounts' tblproperties("parquet.compression=SNAPPY")
;

insert into temp.accounts partition(areacode='0') values
('David','David','00')
,('Ellen', 'Ellen','00')
,('David','David','00')
,('David', 'David','00');

create external table temp.accounts_nested           (                                                                                                                                                                                     
first_name                  string
,last_name                  string
,zipcode                  string
)
partitioned by (areacode string)
stored as parquet location '/temp.db/accounts_nested' tblproperties("parquet.compression=SNAPPY")
;

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

insert overwrite table temp.accounts_nested 
partition(areacode)
select first_name, last_name, zipcode, areacode from temp.accounts;

输出：

select * from temp.accounts_nested;
