Ning Zhang commented on HIVE-1082:
----------------------------------
Venky, following is what specified in the HiveQL language manual (DDL):
CREATE TABLE creates a table with the given name. An error is thrown if a table
or view with the same name already exists. You can use IF NOT EXISTS to skip
the error.
So I think what you want is implemented in the plain create table T DDL?
> "create table if not exists " should check if the specified schema matches
> the existing schema, and throw an error if it doesnt.

> I think we should make sure that the table can either be created anew with
> the specified properties, or it already exists with those properties, where
> 'properties' includes all metadata except timestamps. Anything else is an
> error. This makes sense if you think of a table as the name + its schema,
> instead of the name alone.
