Subject: [Analytics] All the nodes in the Analytics Hadoop cluster will be rebooted today
To: "A mailing list for the Analytics Team at WMF and everybody who has an interest in Wikipedia and analytics." <analytics@lists.wikimedia.org>, research-internal@lists.wikimedia.org


Hi folks! 

Due to a kernel upgrade for a security fix we need to reboot each node of the Hadoop cluster. The task will be started later on today and it will be done in small batches to avoid causing major delays to outstanding jobs. Please contact me if you notice any major issue (elukey or the #wikimedia-analytics channel on freenode).

Thanks!

Regards,

Luca
