Session level metastore
-----------------------
Key: HIVE-805
URL: https://issues.apache.org/jira/browse/HIVE-805
Project: Hadoop Hive
Issue Type: New Feature
Components: Query Processor
Affects Versions: 0.5.0
Reporter: Ashish Thusoo
Assignee: Ashish Thusoo
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.
