[Engineering] [Analytics Cluster] Downtime announcement for Oozie/Hive - Dec 7 10AM CET

[Luca Toscano]

Hi everybody,

we are experiencing some issues with the Hive daemon, so currently Hive
queries are not available. I am going to update this thread as soon as the
issue is over.

For more info, please contact me (elukey) on IRC (#wikimedia-analytics).

Sorry for the trouble!

Luca
