Question on Mesos 1.1.0 LaunchGroup

[Qi Feng]

I'm trying the LaunchGroup feature.

But I find the an executorInfo is required.


    message LaunchGroup {
      required ExecutorInfo executor =3D 1;
      required TaskGroupInfo task_group =3D 2;
    }

What's more, an executor id is required in executorInfo. How would I build =
the executorInfo if I use the default executor of mesos?

Thanks for any reply.
