Antoine Pitrou commented on ARROW-473:
--------------------------------------
Is this still desirable? Note that we may not keep the old HDFS API exposed.
The new API uses the FileSystem abstraction.
> [C++/Python] Add public API for retrieving block locations for a particular
> HDFS file

> This is necessary for applications looking to schedule data-local work.
> libhdfs does not have APIs to request the block locations directly, so we
> need to see if the {{hdfsGetHosts}} function will do what we need. For
> libhdfs3 there is a public API function
