Description

CREATE EXTERNAL TABLE doesn't work as before since Spark 3.0.0 preview 2. 

SPARK-30098 describes the goal as `spark.sql.source.default` as default provider if there's no explicit "USING provider", but parser rule seems to be modified more than the goal which breaks CREATE EXTERNAL TABLE.

scala> sql("CREATE EXTERNAL TABLE aaa (key INT, value STRING) USING HIVE LOCATION '/tmp/aaa'")
org.apache.spark.sql.catalyst.parser.ParseException:
Operation not allowed: CREATE EXTERNAL TABLE ...(line 1, pos 0)
== SQL ==
CREATE EXTERNAL TABLE aaa (key INT, value STRING) USING HIVE LOCATION '/tmp/aaa'

It requires unique option for Hive table to let parser use the rule for Hive table. For example, STORED AS would work.
