Answer 2

探索後，我得到了答案。

create table table (id string) partitioned by (value string) stored as ORC tblproperties ("orc.compress" = "SNAPPY"); 


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

SET hive.exec.max.dynamic.partitions=2048; 
SET hive.exec.max.dynamic.partitions.pernode=256; 

INSERT INTO table1 PARTITION (value) 
select * from table where value is not NULL;
