I have two users. (A, B)
And I have two hive databases (a_db, b_db)

I gave ‘read’ authorization to A user only for a_db.
And I didn’t give any authorizations to B user.

But when A user connected to Hive server by using JDBC/ODBC in DBever or PowerBI, he can see b_db too. he can all databases and tables.
B user too.

Do I need to use LDAP or Kerberos to apply the Ranger authorization to Hive db/table?

I would appriciate if someone answer my question.

Thanks.
