query = """CREATE TABLE IF NOT EXISTS {}
           USING PARQUET 
           LOCATION '{}'""".format(raw_table,s3_bucket_location)

but I am not happy with the schema it infers from the parquet, Is there a way I can enforce schema on this table by changing some column types ? I tried by add the 
options ( schema = <schema_definition> ) to the create command, that didnt work.
