Hiya,
We’re ready to upgrade the Analytics Cluster to CDH 5.5. To do so, we need
to schedule a maintenance period during which we can stop all Hadoop
related services. This includes Hive, Oozie, Spark, etc.
I’d like to plan this for Tuesday February 23rd starting at 14:00 UTC
(09:00 US east coast, 06:00 US west coast). We’ve practiced this upgrade a
few times in labs now, and I don’t foresee any issues. I predict that it
will take us no more than 2 hours to finish, but just in case I’d like to
reserve 8 hours for this.
Please plan on not using the Analytics Cluster between 14:00 and 22:00 on
February 23rd. I will update this thread again when we are about to start,
and when we are finished.
Progress is being tracked here:
