Hi everybody, maintenance just completed, it took a bit more but no issue registered so far. We weren't able to swap analytics1003 (where Oozie/Hive/etc..) in this maintenance window, so I'll likely send another email next week to schedule downtime (not for the entire cluster but mostly for Hive/Oozie only), please don't hate me :)
If you see any issue please contact us (via https://phabricator.wikimedia.org/T203635 or IRC Freenode #wikimedia-analytics). Thanks!
