> The following DDL for a managed table with an existed default location should 
> throw an exception:
> {code}
> CREATE TABLE ... (PARTITIONED BY ...) AS SELECT ...
> CREATE TABLE ... (PARTITIONED BY ...)
> {code}
> Currently there are some situations which are not consist with above logic:
> 1. CREATE TABLE ... (PARTITIONED BY ...) succeed with an existed default 
> location
> situation: for both hive/datasource(with HiveExternalCatalog/InMemoryCatalog)
> 2. CREATE TABLE ... (PARTITIONED BY ...) AS SELECT ...
> situation: hive table succeed with an existed default location
