Hi everybody, the Analytics team will shutdown completely the Hadoop cluster for a couple of hours on Monday Nov 12th at 14:00 CEST to upgrade the Cloudera distribution to 5.15 (currently 5.10). No big updates but only a collection of small/medium fixes that (hopefully) will improve the reliability of our cluster. For more info, please check https://phabricator.wikimedia.org/T204759. This means that tools like HDFS, Hive, Oozie, etc.. will not be available during the maintenance window, so if this impacts your work please reach out to us so we can chat about it and possibly re-schedule if needed (in the task or #wikimedia-analytics on Freenode IRC). Thanks a lot for the patience, we are trying to do our best to keep all our systems as up to date as possible :) Luca (on behalf of the Analytics team)
