    Description

      While we've done some good work with better handling when Spark is choosing to decommission nodes (SPARK-7955), it might make sense in environments where we get preempted without our own choice (e.g. YARN over-commit, EC2 spot instances, GCE Preemptiable instances, etc.) to do something for the data on the node (or at least not schedule any new tasks).
