Hi everybody,
the day has finally come, we'll start the procedure at around 13:00 CET.
For any issue please reach out to the Analytics team on Freenode
(#wikimedia-analytics) or
We hope to have the cluster back running in a couple of hours, but it might
take more if we encounter unexpected issues.
Thanks for the patience!
Luca

Hi everybody,
to avoid any conflict with the start of the Fundraising season, we moved
the Kerberos maintenance to Dec 16th at 10 AM CET (more info in
https://phabricator.wikimedia.org/T238560).
If you use Hadoop and you haven't requested credentials yet, please do so
following

Hi everybody,
the Analytics team is going to enable Kerberos authentication for Hadoop
on Monday December 2nd. The procedure will start around 10 AM CET and will
hopefully last 3/4 hours, but since this is an invasive change there might
be a possibility that it will last more. If you have anything important
that requires Hadoop on this date please let us know in advance.
The most visible change from the user's point of view is the introduction
of a new account/password to be able to use the Hadoop services (like
Hive/HDFS/Spark/Oozie). We created a user guide about what will change with
kerberos in
https://wikitech.wikimedia.org/wiki/Analytics/Systems/Kerberos/UserGuide.
There is also a task opened to track any doubt/question/special-use-cases
during the next two weeks:
https://phabricator.wikimedia.org/T238560.
Feel free to reach out to IRC #wikimedia-analytics on Freenode too!
Thanks!
