Peter Vary commented on HIVE-19569:
-----------------------------------
[~maheshk114]: We proposed exactly this kind of standardisation, but finally
the community decided against it. So it might be good idea to stick to the
original decision or discuss it again on the dev list in case we find a strong
enough case for it.

> When renaming a table within the same DB, this operation causes
> {{MetaStoreEventListener.onAlterTable()}} to fire but when changing DB name
> for a table it causes {{MetaStoreEventListener.onDropTable()}} +
> {{MetaStoreEventListener.onCreateTable()}}.
> The files from original table are moved to new table location.
> This creates confusing semantics since any logic in {{onDropTable()}} doesn't
> know about the larger context, i.e. that there will be a matching
> {{onCreateTable()}}.
> In particular, this causes a problem for Acid tables since files moved from
> old table use WriteIDs that are not meaningful with the context of new table.
> Current implementation is due to replication. This should ideally be changed
> to raise a "not supported" error for tables that are marked for replication.
