So we have 3 cases:
1. Tables created with Hive syntax -- we generate DDL in hive syntax
2. Tables created with datasource syntax -- we generate DDL in datasource
syntax `...USING...OPTIONS(...)`
3. Tables created from dataframe -- If the table metadata contains the
features that are not supported in datasource syntax, generate create table
with dataframe API. The reason for this condition is that under the cover there
is no indication of whether the table is created with dataframe API or not, it
is just a datasource table by `spark.sql.sources.provider`.
@yhuai what do you think? Thanks!
