Hi @idzikovsky , thanks for submitting the PR. It got lost among all the stale PRs, but now that many of those are closed, I saw this was still open. Could you please add the "## Was this patch authored or co-authored using generative AI tooling?" section in the PR description and could you please also create a JIRA for it? If those are done, this PR could be merged.

@gyogal

Sure. Done. Thank you!

Thanks for the updates @idzikovsky , the PR looks good now! Also, there have been a few other Kerberos related PRs opened and merged recently by different contributors, if you have some time, please check them out to see if those are working for your use case. Many thanks!

There were already following properties added into livy.conf:

# Authentication support for Livy server
# Livy has a built-in SPnego authentication support for HTTP requests  with below configurations.
# livy.server.auth.type = kerberos
# livy.server.auth.kerberos.principal = <spnego principal>
# livy.server.auth.kerberos.keytab = <spnego keytab>
# livy.server.auth.kerberos.name-rules = DEFAULT

Those are properties which configures the HTTP/host@REALM principal used for Livy HTTP server (for inbound SPNEGO authentication).

The properties in this PR configures the Kerberos credentials for the Livy Server itself so it will be able to communicate with KDC and start kinit thread:

Anyway, thank you!
