test mode in hive
-----------------
Key: HIVE-518
URL: https://issues.apache.org/jira/browse/HIVE-518
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.3.1
Reporter: Namit Jain
Assignee: Namit Jain
Fix For: 0.4.0
Attachments: hive.518.1.patch
It would be good to have a test mode in hive - this will help in checking the
validity of a hive drop on a production cluster.
The following would be good to have:
Testmode --> In testmode, all input tables are sampled (if not already sampled)
and all output tables are prefixed by a user supplied name.
This way, multiple hive drops can be compared quickly for correctness
