>
> Hive caches object inspector in memory to avoid recreating the same object.
> However, in {{ArrayWritableObjectInspector}}, the {{equals}} and {{hashCode}}
> doesn't take account on all attributes of the class, therefore, even though
> the internal state (e.g., {{adjustedIndex}}) is different, it could still be
> mapped to the same result. This could cause wrong field index being used when
> reading Parquet data.
