viirya opened a new pull request #24938: [SPARK-27946][SQL] Hive DDL to Spark DDL conversion USING "show create table" URL: https://github.com/apache/spark/pull/24938 ## What changes were proposed in this pull request? This patch adds a DDL command `SHOW CREATE TABLE AS SPARK`. It is used to generate Spark DDL for a Hive table. For Hive serde to data source conversion, this uses the existing mapping inside `HiveSerDe`. If can't find a mapping there, throws an analysis exception on unsupported serde configuration. It is arguably that some Hive fileformat + row serde might be mapped to Spark data source, e.g., CSV. It is not included in this PR. Can be a follow-up. For Hive serde properties, for now this doesn't save it to Spark DDL because it may not useful to keep Hive serde properties in Spark table. ## How was this patch tested? Added test.
