Peter Bacsko commented on YARN-9477:
------------------------------------
Test failure seems to be unrelated to this patch. Instead, it was most likely
caused by a recent commit (YARN-6929).
[~Prabhu Joseph] could you please investigate this test failure?

> Implement VE discovery using libudev
> ------------------------------------

> Key: YARN-9477
> URL: https://issues.apache.org/jira/browse/YARN-9477
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Peter Bacsko
> Assignee: Peter Bacsko
> Priority: Major
> Attachments: YARN-9477-001.patch, YARN-9477-002.patch,
> YARN-9477-POC.patch, YARN-9477-POC2.patch, YARN-9477-POC3.patch

> Right now we have a Python script which is able to discover VE cards using
> pyudev: https://pyudev.readthedocs.io/en/latest/
> Java does not officially support libudev. There are some projects on Github
> (example: https://github.com/Zubnix/udev-java-bindings) but they're not
> available as Maven artifacts.
> However it's not that difficult to create a minimal layer around libudev
> using JNA. We don't have to wrap every function, we need to call 4-5 methods.
