The spark.sql accepts the to_timestamp function inside the spark function and converts the given column in the timestamp. Parquet is a columnar format that is supported by many other data processing systems. But with to_date, if you have issues in parsing the correct year component in the date in yy format (In the date 7-Apr-50, if you want 50 to be parsed as 1950 or 2050), refer to this stackoverflow post See Datetime patterns for details on valid formats..
