Hi Niklas, Thanks for the response.
Actually I have an Instance of a framework running. The framework is in C++. I registered the framework with mesos. I am getting resource offers offered by Apache mesos. For getting resources, I sent the "this" pointer of the instance to the class which implements our mesos scheduler interface. I have launch the task taken from the "this" pointer. I am perplexed how to proceed. The instance of framework has no serialization implementation. My task is to carry the instance of framework to the executor and then call a method from the task data given in scheduler of mesos. J.
