----------------------------------

Hi [~winipanda], I'm working on this and will assign this ticket to myself. 
It's more than welcome if you'd like to participate into the flink-hive 
integration project, let Xuefu and I know and we can figure out something for 
you to work on.

Thanks, Bowen

>          Components: Table API & SQL
>    Affects Versions: 1.6.1

> Currently {{TableEnvironment}} manages a list of registered external catalogs 
> as well as in-memory meta objects, and interacts with Calcite schema. It 
> would be cleaner to delegate all those responsibilities to a dedicate class, 
> especially when Flink's meta objects are also stored in a catalog.
> {{CatalogManager}} is responsible to manage all meta objects, including 
> external catalogs, temporary meta objects, and Calcite schema.
