Venky Iyer commented on HIVE-1082:
----------------------------------
Talked to Prasad a little more about this:
1) The expectation is that the table that will exist after 'CREATE TABLE IF NOT
EXISTS' is a combination of the specified schema + properties, plus the default
properties when not specified. We should enforce this
2) Current code may break if we turn this on, so maybe we should have a CREATE
TABLE IF NOT EXISTSWITHSCHEMA statement, or a strict mode of some sort.
> "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.
