add database/scheme support Hive QL
-----------------------------------
Key: HIVE-675
URL: https://issues.apache.org/jira/browse/HIVE-675
Project: Hadoop Hive
Issue Type: New Feature
Components: Query Processor
Reporter: Prasad Chakka
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.
