> Currently all Hive tables reside in single namespace (default). Hive should
> support multiple namespaces (databases or schemas) such that users can create
> tables in their specific namespaces. These name spaces can have different
> warehouse directories (with a default naming scheme) and possibly different
> properties.
> There is already some support for this in metastore but Hive query parser
> should have this feature as well.
