Hi Goran,

sorry for the delay but this morning we didn't manage to drain the cluster and reboot, I am going to do it now. It should take a maximum of 2 hours from now. Apologies for the inconvenience.

Hi,

I am sorry if it turns out that you have already informed us about this: please, is the cluster reboot completed?

I have a lot of Hive jobs waiting. 

Thanks, 

Goran

Hi again,

the maintenance didn't happen because we currently have important Spark jobs that need to finish, so if nobody opposes I'd like to move it to Monday (Sept 10th, EU morning time).

As always please follow up with me in https://phabricator.wikimedia.org/T203165 or IRC if this affects your work :)

Thanks and sorry for the late notice!

Hi everybody,

just wanted to let you know that tomorrow morning EU time I'll stop Hive and Oozie on analytics1003 (Hadoop Cluster) to allow the host to be rebooted. I don't plan to kill any job but to wait for their completion. While the maintenance happens some errors might happen to your jobs. The reboot should take some minutes to complete if everything goes as planned.

Tracking task: https://phabricator.wikimedia.org/T203165

Please let me know on IRC or in the task if this affects you :)
