Till, You got it, that is exactly what I need. I guess I will have to implement an anonymous module even though the documentation warns you against it :) Oscar

Maybe you should consider using a module for this. There is this notion of so called anonymous modules. Such module simply coexists with the parent process, in your case the agent.See http://mesos.apache.org/documentation/latest/modules/ for more. Such module in combination with a custom executor might get you where you need to be…. at least that is what I am hoping for.

I am trying to avoid sending a bogus initial task just to kick it off, but it seems there is no way to tell the mesos-slave to start the executor at startup, is it?

The built in executors self-terminate after running the tasks they are launched with.

The service takes into account who and how many are out there and some information from the HB to perform some sort of load balancing. Without the HB the service does not know how many agents are out and tasking is assigned only when an offer is received, but that is not as effective as it should be if the service would know in advance about the cluster's load.

In your case, what is the heartbeat for, if there are no tasks on the agent? J
