The Analytics team is planning to upgrade OpenJDK in our Hadoop cluster (https://phabricator.wikimedia.org/T229003) tomorrow Tuesday 30th of July at 10am CEST.

Hive and Oozie will be unavailable for 10 to 15 minutes, and any ongoing Oozie jobs or Hive (beeline) queries will be interrupted (we'll let the outstanding ones finish, if possible).

If this will break some important job that you have running, please let us know in the Phabricator task above or via IRC (#wikimedia-analytics).

Cheers!
