Hi all,
We will be draining the hadoop cluster of jobs Tuesday May 25 starting at
15:00 UTC (8am PDT) for another attempt to update the operating system of
the namenodes. The first time around, we encountered an issue and called
off the update. This time, I'm estimating the maintenance will last 3
hours. We'll announce when the queue is back to accepting jobs.
