Zhihua Deng updated HIVE-28460:
-------------------------------
Description:
Upon ObjectStore initialization, we need to determine which type of underlying
db is by asking the connection the product name. It's a waste of time and
resource to do this, as long as we don't change the database connection
information, the db type shouldn't be changed, sometimes
1. Determine the database product once instead of every time on ObjectStore
initialization;
2. Extract the ObjectStore methods designed for HiveMetaTool to a standalone
class;
3. Remove some dangling codes.
