orc是支持的,202309版本说支持了parquet,实际上又没支持,感觉有点奇怪

https://github.com/alibaba/DataX/blob/master/hdfsreader/doc/hdfsreader.md

HdfsReader提供了读取分布式文件系统数据存储的能力。在底层实现上,HdfsReader获取分布式文件系统上文件的数据,并转换为DataX传输协议传递给Writer。

目前HdfsReader支持的文件格式有textfile(text)、orcfile(orc)、rcfile(rc)、sequence file(seq)和普通逻辑二维表(csv)类型格式的文件,且文件内容存放的必须是一张逻辑意义上的二维表。

HdfsReader需要Jdk1.7及以上版本的支持。

里面好像没说有parquet
