> Hive recently moved its processing to the proleptic calendar, which has
> created some issues for users who have dates before 1580 AD.
> Hive最近将其处理移到了proleptic日历上，这给日期在公元1580年之前的用户带来了一些问题。
> HIVE-22405 extended the column vectors for times & dates to encode which
> calendar they are using.
> HIVE-22405扩展了时间和日期的列向量&，以编码它们所使用的日历。
> This issue is to support proleptic calendar in ORC, Parquet, and Avro, when
> files are written/read by Hive. To preserve compatibility with other engines
> until they upgrade their readers, files will be written using hybrid calendar
> by default. Default behavior when files do not contain calendar information
> in their metadata is configurable.
> 当文件由Hive写入/读取时，此问题用于支持ORC、Parquet和Avro中的proleptic日历。为了在升级阅读器之前保持与其他引擎的兼容性，默认情况下将使用混合日历写入文件。当文件的元数据中不包含日历信息时，默认行为是可配置的。
