Description

It would be useful if Hive could infer the column definitions in a create table statement from the underlying data file. For example:

CREATE TABLE new_tbl LIKE PARQUET '/path/to/file.parquet';

If the targeted file is not the specified file format, the statement should fail analysis. In addition to PARQUET, it would be useful to support other formats such as AVRO, JSON, and ORC.
