Paul Lin updated FLINK-17091:
-----------------------------
Description:
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. When encountering objects of the new physical classes,
AvroRow(De)SerializationSchema just ignores them and passes them to Avro's
GenericDatumWriter, which leads to ClassCastException thrown by
GenericDatumWriter. See
[AvroRowSerializationSchema|https://github.com/apache/flink/blob/master/flink-formats/flink-avro/src/main/java/org/apache/flink/formats/avro/AvroRowSerializationSchema.java#L251].
