Hive does not have a ```NATURAL``` keyword. It behaves the same as the old
SqlParser:
- It will either treat ```NATURAL``` the alias of the previous table, eg:
```select * from db.a natural join db.b```
- It does not recognize the input at ```NATURAL``` and throws a
```ParseException```, eg: ```select * from db.a as x natural join db.b```
