Description

Currently catalog API has get/setCurrentDatabase(), which is more user session specific. In our design principal, catalog instance is agnostic to user sessions. Thus, current database concept doesn't belong there. However, a catalog should support a (configurable) default database, which would be taken as user's current database when user's session doesn't specify a current DB.

This JIRA is to remove current database concept from catalog api and add default database instead.
