Description
For self-describing formats like ORC, it should be possible to create a table from a file without explicitly specifying the schema. It would be useful for debugging, but also for all kinds of ad-hoc activities with data (and I bet someone will also use it for ETL, sadly 
).
The schema should be established in metastore as the final schema for the table; it should not be an attached+derived schema, like for Avro.
