> 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.
