Neal Richardson commented on ARROW-5995:
----------------------------------------
It sounds like you already know more about HDFS checksums, but
[https://wesmckinney.com/blog/python-hdfs-interfaces/] may also be interesting
reading for you. You may need to look into what libhdfs(3) provide.
> [Python] pyarrow: hdfs: support file checksum

> Key: ARROW-5995
> URL: https://issues.apache.org/jira/browse/ARROW-5995
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Ruslan Kuprieiev
> Priority: Minor
>
> 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?
