We have tested this with our own catalog integration, and keep the table
name should work. The sub catalog which representing the database layer can
concat the db and table name when creating Table instance.

> Issue Type: Bug
> Components: Table API & SQL

> Assignee: Haohui Mai
> Priority: Critical
> Fix For: 1.3.0

>
> We found out that the current external catalog requires three layers of
> references for any tables. For example, the SQL would look like the following
> when referencing external table:
> {noformat}
> SELECT * FROM catalog.db.table
> {noformat}
> It would be great to support only two layers of indirections which is closer
> to many of the deployment on Presto / Hive today.
> {noformat}
> SELECT * FROM db.table
> {noformat}
