Subject [jira] Commented: (HIVE-675) add database/scheme support Hive QL
Date Thu, 10 Sep 2009 23:35:57 GMT

    [ https://issues.apache.org/jira/browse/HIVE-675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753897#action_12753897

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

>>if approach A for HIVE-584 is chosen then shouldn't the current patch work without
any changes? 
yes, it will work without changes.
But Hive is now a thread local obj itself, so just as Zheng said, we don't need to protect
the current database with another level of ThreadLocal.

> 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.
