> AvroRow(De)SerializationSchema doesn't know how to convert the new physical 
> classes of Timestamp (eg. java.time.Date) to/from Avro's int/long based 
> timestamp. Currently, when encountering objects of the new physical classes, 
> AvroRow(De)SerializationSchema just ignores them and passes them to Avro's 
> GenericDatumWriter/Reader, which leads to ClassCastException thrown by 
> GenericDatumWriter/Reader. See 
> [AvroRowSerializationSchema|https://github.com/apache/flink/blob/master/flink-formats/flink-avro/src/main/java/org/apache/flink/formats/avro/AvroRowSerializationSchema.java#L251].
> To fix this problem, we should support LocalTime/LocalDate/LocalDateTime 
> conversion to long in AvroRowSerializationSchema, and support long conversion 
> to LocalTime/LocalDate/LocalDateTime based on logical 
> types(Types.LOCAL_TIME/Types.LOCAL_DATE/Types.LOCAL_DATE_TIME) in 
> AvroRowDeserializationSchema.
