Analytics Hadoop cluster full shutdown scheduled for Sept 25th

Luca Toscano
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
