ashleycoxley opened a new issue #475: TimestampWriter isn't being used
URL: https://github.com/apache/incubator-iceberg/issues/475
 
 
   When trying to write to a field with type `Types.TimestampType.withoutZone()`, I'm getting the exception 
   `java.time.LocalDateTime cannot be cast to java.time.OffsetDateTime`. This appears to be due to a case match miss in the `GenericParquetWriter` - for all primitives of type `TIMESTAMP_MICROS`, the `TimestamptzWriter` is returned. I believe it should only be returned when `shouldAdjustToUTC` is true; and the `TimestampWriter` returned otherwise  (similar to the implementation in `GenericParquetReaders`).
