Subject [jira] Commented: (HIVE-675) add database/schema support Hive QL
Date Wed, 29 Sep 2010 00:51:44 GMT


Carl Steinbach commented on HIVE-675:

@Ning: Can you please delete metastore/src/test/org/apache/hadoop/hive/metastore/

In the backport patch this file is deleted and replaced with,
but it looks like for some reason 
this file was not actually deleted when the patch was applied.

> 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.
