What do you say on the Internet? jdbc package, but I let go, and I have mysql configuration users, and I still can't match it.

Solution to the problem:

The problem has been solved. At first, there was no history. I suspect it was the hive version. Sure enough, I changed the hive-0.9.0 and reinstalled it again.

As for showtables, the permissions in mysql are not properly configured. At first, according to the things on the Internet, the% number of create user 'hive'@'%' is not the same as the jdbc configured in that hive-site.xml, so I simply replaced it with localhost, and then created my own database hive with hive users. It seems that I have to use hive users to create their own database. Then I started knocking, such as show tables, for a while, and then suddenly ok appeared when I thought it would not be successful. Here, I thought about it carefully. It may be a permission problem, because the user name and password we used during configuration are in mysql. If the permissions are not correct, they cannot be connected.
