Thank you Qian, Yes, I believe a framework is needed for handling my case. I was just wondering if it could be possible to simply execute one specific command in multiple agent nodes using current mesos-execute command.
In relation to your last comment, it does make sense to launch one task on multiple nodes: think about fault tolerance, where one needs replicas in case of failures in the datacenter.
