> Components: Metastore, Parser, Security, SQL
> Affects Versions: 3.0.0

> SQL supports two levels of namespaces, called in the spec catalogs and schemas (with schema being equivalent to Hive's database). I propose to add the upper level of catalog. The attached design doc covers the use cases, requirements, and brief discussion of how it will be implemented in a backwards compatible way.
