--Good morning,
I have to find a convenient time to reboot a key server (an-coord1001) which supports the analytics services.
Unfortunately, although we have a standby server, the process for switching the two servers' roles is somewhat arduous so the pragmatic option is to schedule a brief period of downtime for the affected services, while the primary server is rebooted. These services are: Hive, Superset, Oozie, Presto, and DataHub.
The outage should last for less than 10 minutes and I propose to carry out this maintenance at 09:00 UTC tomorrow - May 5th.
Please do let me know if this is going to impact you negatively and I will try to find another maintenance window. If you have any other queries or concerns, please don't hesitate to get in touch.
Thanks and best wishes,
Ben
