Ning Zhang commented on HIVE-1082:
----------------------------------

@venky, I am a little bit confused about the requirement. Do you mean we should 
allow the following situation: Table T(a int, b string) and table T (a int, b 
string, c string) exist in the same database? If so, what is the semantics of 
'select a, b from T;'?

> "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.
