分区在Hive2.3.0中不起作用

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。。

在Hive1.x上同样成功

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。
