    @tnachen For some reason the shutdown hooks are not finishing properly if it receives a SIGTERM during shutdown. See logs in https://issues.apache.org/jira/browse/SPARK-12330 where `INFO CoarseGrainedExecutorBackend: Driver commanded a shutdown` is followed by a `ERROR CoarseGrainedExecutorBackend: RECEIVED SIGNAL 15: SIGTERM`
    
    Fixing that may be a better root cause fix, but I haven't looked into the hadoop shutdown hooks enough to know where the issue could be with that.
