> I was not able to find how to retrieve checksum (`getFileChecksum` or `hadoop fs/dfs -checksum`) for a file on hdfs. Judging by how it is implemented in hadoop CLI [1], looks like we will also need to implement it manually in pyarrow. Please correct me if I'm missing something. Is this feature desirable? Or was there a good reason why it wasn't implemented already?
