Hey All, I have a Spark cluster(running version 1.5.0) on EC2 launched with the provided spark-ec2 scripts. If I want to upgrade Spark to 1.5.2 in the same cluster, what's the safest / recommended way to do that?
I know I can spin up a new cluster running 1.5.2, but it doesn't seem efficient to spin up a new cluster every time we need to upgrade.
