> Key: FLINK-17091
> URL: https://issues.apache.org/jira/browse/FLINK-17091
> Project: Flink
> Issue Type: Bug
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
> Affects Versions: 1.10.0
> Reporter: Paul Lin
> Priority: Major
>
> 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 int/long in AvroRowSerializationSchema, and support int/long
> conversion to LocalTime/LocalDate/LocalDateTime based on logical
> types(Types.LOCAL_TIME/Types.LOCAL_DATE/Types.LOCAL_DATE_TIME) in
> AvroRowDeserializationSchema.
