Update:
Due to the big Datacenter Switchover happening next week, we’ve decided to
postpone this a bit. We won’t be doing this downtime on Monday April
17th. Instead, we will do this at 13:30 UTC on Tuesday April 25th.
Thanks all!

Hi all!
As part of our Hadoop Cluster Debian Jessie upgrade, we need to reinstall
the server that acts as a metadata state store for Hive, Oozie and Druid.
To be safe, we plan to take those services plus Pivot (which runs on Druid)
offline during while we reinstall this server. We plan to do this on
Monday April 17th at 13:30 UTC (9:30am US East Coast, 6:30am US West
Coast). We don’t expect more than an hour or two of downtime, but likely
less.
Let us know if there are any objections. Please forward this email to any
relevant folks.
Thanks!
