Subject [jira] [Commented] (HIVE-4847) add rename database functionality
Date Tue, 08 Mar 2016 18:14:40 GMT


Alan Gates commented on HIVE-4847:

I agree that there are parts of the system that this can wreak havoc with, such as replication
and ACID.  But it seems all of the same arguments apply to renaming a table, which Hive supports.

Rather than saying we won't apply the patch because of this we should say we won't apply the
patch until it addresses these areas.  Beyond just ACID and replication the HBase metastore
(in 2.0 only) will also be impacted by this, since it uses the db name as the key for storing
databases, tables, and partitions.
