How to migrate a table of a Hive database to another database
Hello:
How to migrate a table of a Hive database to another database?
For example:
Hive contains two databases: databaseA and databaseB. I want to migrate tableA in databaseA to databaseB. What do I need to do? Can you give me detailed steps?

hi!
Using this method to migrate Hive internal tables is normal, but an error is reported when migrating Hive external tables. The error message is as follows:
Error:Error while compiling statement:FAILED:SemanticException [Error 10134]:ALTER TABLE cannot be used for a non-native table tablename
How to migrate Hive external tables?
thinks.
I am looking forward to your reply！
