To modify SQL statement for creating hudi table based on an existing hudi path.

From:

```sql
create table hudi_tbl using hudi tblproperties (primaryKey='id', preCombineField='ts', type='cow') partitioned by (pt) location '/path/to/hudi'
```

To:
```sql
create table hudi_tbl using hudi location '/path/to/hudi'
```
