Hi everybody,
the Analytics team needs to replace the Hadoop master node hosts (analytics100[1,2]) and the Hive/Oozie host (analytics1003) as part of regular hardware refresh (hosts getting out of warranty). In order to do things safely we decided to proceed with a full cluster shutdown on Sept 25th at 10 AM CEST. The maintenance should last a couple of hours and all there shouldn't be any noticeable change for the Hadoop users.
This means that during the maintenance:
- HDFS will not be available
- Yarn will not be available
- Hive/Spark (cluster mode)/Oozie/etc.. will not be available
Please let us know if this impacts your work in https://phabricator.wikimedia.org/T203635 or on the #wikimedia-analytics Freenode IRC channel.
Thanks a lot!
Luca
