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 https://wikitech.wikimedia.org/wiki/Analytics/Systems/Kerberos/UserGuide#Get_a_password_for_Kerberos

Thanks!

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!
