tomorrow EU morning (Wed Mar 7th) I'd need to reboot stat100[56] and analytics1003 for kernel security updates. Hive and Oozie (Analytics Hadoop cluster) will not be available for a (hopefully) brief period of time. Please let me know if there is an important work that you are doing that cannot be stopped and the maintenance will be postponed accordingly :)

Thanks!
