> The {{TableEnvironment}} holds an internal table catalog to provide SQL and 
> Table API queries access to structured data. At the moment, DataSets, 
> DataStreams, and TableSources which refer to external tables can be 
> registered as tables.
> This issue proposes to implement an interface to connect external catalogs 
> such as Hive's HCatalog or Confluent's SchemaRegistry for Apache Kafka to the 
> {{TableEnvironment}}. With this interface, it should be possible to look-up 
> and access tables which are registered in external catalogs.
