Subject [jira] Commented: (HIVE-805) Session level metastore
Date Thu, 27 Aug 2009 20:58:59 GMT


Prasad Chakka commented on HIVE-805:

we need to do this now since Metastore.createTable() will create the directory for you so
when the session level metastore closes, these directories will be unnecessarily hanging.
didn't look into the code yet.

> Implement a shadow metastore that is in memory and runs for a session. This can contain
definitions for session specific views that can be used to implement data flow variables in
Hive. It can also be used for testing scripts. First we will support the later use case where
in all the DDL statements in the session create objects in the session metastore and all the
queries are converted to explain internal. Any thoughts on load commands?
> This feature is enabled when
> set hive.session.test = true
> is done in the session.
