Paul Yang commented on HIVE-675:
--------------------------------

@Carl, do you happen to have a MySQL upgrade script for adding the new tables / columns required
to support this feature?

> 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.
