hadoop - 插入到配置单元分区表中 SemanticException

Question

首先我创建了一个 Hive 分区表:

hive> create table partition_table
    > (sid int ,sname string ,age int)            
    > partitioned by (sex string)     
    > row format delimited fields terminated by',';  
OK
Time taken: 1.232 seconds

表格描述如下:

 hive> desc partition_table;
    OK
    sid                     int                                         
    sname                   string                                      
    age                     int                                         
    sex                     string                                      

# Partition Information      
# col_name              data_type               comment             

sex                     string                                      
Time taken: 0.34 seconds, Fetched: 9 row(s)

然后我将一些数据插入到该表中，但它不起作用。

hive> insert into table partition_table partition(sex='M')select sno ,sname ,age from student1 where sex ='M';
FAILED: SemanticException [Error 10006]: Line 1:44 Partition not found ''M''

为了避免这种情况，我编写了以下命令，然后执行了我的插入命令，即使这样我也反复遇到同样的错误。

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

Answer 1

加载前添加分区:

ALTER TABLE partition_table ADD PARTITION( sex= 'M' );
insert into table partition_table partition(sex='M') select sno ,sname ,age from student1 where sex ='M';

或尝试动态分区:

set hive.exec.dynamic.partition=true;
INSERT OVERWRITE TABLE partition_table PARTITION (sex)
SELECT sid, sname, age, sex
FROM student1;
