rdblue commented on issue #28026: [SPARK-31257][SQL] Unify create table syntax (WIP) URL: https://github.com/apache/spark/pull/28026#issuecomment-606733289 > Hive has more features (more flexible parser) than Spark, but it doesn't mean Spark needs to accept them all. I don't think Spark needs to make a choice on this for the v2 API. It is up to the catalog what features of a table format are useful or not. Because Spark supports parsing EXTERNAL, it makes no sense to arbitrarily suppress it. That requires _more_ code in Spark that is specific to what is now a responsibility delegated to a catalog. It breaks the abstraction.
