[jira] [Updated] (YARN-9477) Investigate device discovery
mechanisms
[ https://issues.apache.org/jira/browse/YARN-9477?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Peter Bacsko updated YARN-9477:
-------------------------------
Description:
Right now we have a Python script which is able to discover VE cards using pyudev.
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 terribly 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.
