Hive分区表创建，增加及删除

1.创建Hive分区表，按字段分区

CREATE TABLE test1 (   id bigint ,   create_time timestamp ,   user_id string)   partitioned by (partition_key int)   ROW FORMAT DELIMITED    FIELDS TERMINATED BY ‘\001‘   LINES TERMINATED BY ‘\n‘; 

2.增加Hive分区表

ALTER TABLE test1 ADD PARTITION(partition_key=20180620) LOCATION ‘/user/hive/warehouse/demo.db/test1/partition_key=20180620‘;     

3.删除分区Partition

alter table user_behaviour drop partition(partition_key=20180620);
