Hi all,

We will be draining the hadoop cluster of jobs Tuesday May 25 starting at 15:00 UTC (8am PDT) to update the operating system of the namenodes. Maintenance should last less than 2 hours, and we'll announce when the queue is back to accepting jobs.

View planned maintenance here. Reply to this email or comment on the task at https://phabricator.wikimedia.org/T278423 if you have any questions or concerns.

This maintenance could be done without downtime but I'm opting to drain the cluster to make for an easier recovery in case anything goes wrong.
