[jira] [Created] (HIVE-10593) Support creating table from a file
schema: CREATE TABLE ... LIKE '/path/to/file'
Lenni Kuff created HIVE-10593:
---------------------------------
Summary: Support creating table from a file schema: CREATE TABLE ... LIKE <file_format> '/path/to/file'
Key: HIVE-10593
URL: https://issues.apache.org/jira/browse/HIVE-10593
Project: Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 1.2.0
Reporter: Lenni Kuff
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.
