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!
Luca

Hi everybody,
the Analytics team needs to replace the Hadoop master node hosts
(analytics100[1,2]) and the Hive/Oozie host (analytics1003) as part of
regular hardware refresh (hosts getting out of warranty). In order to do
things safely we decided to proceed with a full cluster shutdown on Sept
25th at 10 AM CEST. The maintenance should last a couple of hours and all
there shouldn't be any noticeable change for the Hadoop users.
This means that during the maintenance:
- HDFS will not be available
- Yarn will not be available
- Hive/Spark (cluster mode)/Oozie/etc.. will not be available
Please let us know if this impacts your work in
https://phabricator.wikimedia.org/T203635 or on the #wikimedia-analytics
Freenode IRC channel.
Thanks a lot!
Luca
