HeartSaVioR commented on issue #28026: [SPARK-31257][SQL] Unify create table 
syntax (WIP)
URL: https://github.com/apache/spark/pull/28026#issuecomment-605538309
 
 
   Same here, please describe TODO list for this PR to remove WIP.
   
   If I skimmed the code correctly, this "requires" end users to add `USING 
hive` even they add Hive create table specific clause. Do I understand 
correctly?
   
   It's OK if that's one of TODO - we should concern about documentation to 
make clear which clause changes the provider. (Personally I'm not in favor of 
this, but otherwise why not just add `HIVE` to second syntax as both are 
requiring end users to change their query and adding `HIVE` is clearer?)
   
   If the change is intentional, that's my favor but I may concern about 
removing compatibility flag, as this will force end users to migrate their 
query in any way.
