Good news everyone, we enabled Kerberos!
If you use the Hadoop cluster in any way, you'll need to kinit to get a Kerberos token so you can authenticate yourself or your job. Here's the guide again: https://wikitech.wikimedia.org/wiki/Analytics/Systems/Kerberos/UserGuide.
If you use our APIs or datasets, these are coming back online and updating slowly since we paused them early today. Expect a bit more lag, but that should clear within a few days as jobs catch up.
Let us know if you need any help on Phabricator, at https://phabricator.wikimedia.org/T238560. And as always find us on IRC, #wikimedia-analytics.
