@shenh062326 Thanks for your work. However, the approach here won't
actually work for standalone or Mesos mode. In general once the executor is
launched the driver doesn't really have much control over it. In order to do
anything to kill it we need a cluster manager specific solution. For instance,
in standalone mode we need a hook in the `Worker` to kill the executor. This
pathway currently doesn't exist, so this patch is not really meaningful until
that is implemented.
Since there is not a clear timeline for when that will be in place, I would
recommend that we close this PR for now and keep the JIRA open because
eventually we may actually want to do this.
