------------------------------------------

Thanks Ning, That makes sense, At the moment we have added code to log a WARN, 
but using Create or replace table is the right approach as you suggest, will 
update if we get this done..

> "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.
