Subject [jira] Commented: (HIVE-675) add database/scheme support Hive QL
Date Tue, 15 Sep 2009 06:33:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755384#action_12755384

He Yongqiang commented on HIVE-675:
-----------------------------------

There are two classes SessionState refers may block moving SessionState from ql to common,
Utilities and HiveHistory.
For Utilities, we can split it and add another Utilites to common package. 
But it is not easy for HiveHistory, it refers to QueryPlan and Task, which then refer to many
others...
So i think this would need a refactory of packing?

> 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.
