    I'd prefer to avoid pattern matching on `Option`, so:
    ```scala
    executorDataMap.get(executorId).map { executorInfo =>
      executorInfo.executorActor ! KillTask(taskId, executorId, interruptThread)
    } getOrElse { 
      logWarning(s"Attempted to kill task $taskId for unknown executor 
$executorId.")
    }
    ```
