我创建了如下表:
create table emp (
> eid int,
> fname string,
> lname string,
> salary double,
> city string,
> dept string )
> row format delimited fields terminated by ',';
然后,为了启用分区,我设置了以下属性:
set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
我创建了如下分区表:
create table part_emp (
> eid int,
> fname string,
> lname string,
> salary double,
> dept string )
> partitioned by ( city string )
> row format delimited fields terminated by ',';
在创建表之后,我发出了insert查询
insert into table part_emp partition(city)
select eid,fname,lname,salary,dept,city from emp;
但它不起作用。。

我也有同样的问题
set hive.exec.max.dynamic.partitions.pernode=1000;
(默认值100)解决了我的问题。你可以试试。ps:此设置意味着:允许在每个mapper/reducer节点中创建的最大动态分区数。
