问题 Let's suppose I have two hive tables, table_1 and table_2 . I use: ALTER TABLE table_2 ADD PARTITION (col=val) LOCATION [table_1_location] Now, table_2 will have the data in table_1 at the partition where col = val . What I want to do is reverse this process. I want table_2 not to have the partition at col=val , and I want table_1 to keep its original data. How can I do this? 回答1: Make your table EXTERNAL first: ALTER TABLE table_2 SET TBLPROPERTIES('EXTERNAL'='TRUE'); Then drop partition,
