wesm commented on issue #1031: WIP ARROW-473: [C++/Python] Add public API for
retrieving block locations for a particular HDFS file
URL: https://github.com/apache/arrow/pull/1031#issuecomment-340315909
@AnkitAggarwalPEC would it be OK if I took over developing the patch from
here so we can get this closed out for 0.8.0? I have a local HDFS setup (from
my Apache Impala development environment) I can use for testing. I'm not sure
what's going on with the Docker setup but someone will need to investigate
separately

> 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
