If you have an executor running on a agent, wait for an offer from *that agent* and launch a new task with the *same* ExecutorInfo as the one you originally used to launch the executor. In this case, mesos will not launch a new executor but passes the task to the already running executor. Note that, if for some reason your original executor died just as you were launching the new task, mesos will launch a new instance of that executor and pass the new task. So your executor needs to handle this race.
