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.

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.
