Ok, probably you are right but what you don’t understand is that i am a completely newbie and i see such systems for the first time. It’s about a university project that i am working on in order to get my bachelor degree. I don’t really know the proper way to express what i want to like you do. I don’t know how to connect 2 frameworks or something, i don’t even know how to make my own framework and compile it with the dependencies that Mesos needs. I am just writting on TestFramework.java and TestExecutor.java and that’s all. The reason that i want to run everything from the same framework (instance) is because keep a TreeMap with some info that i don’t want to lose if i terminate the Schedulers driver. So if i start up a new framework, TreeMap is gone. Forget about the tasks, i can use the same TestExecutor.java for every scheduler.
What i want to achieve is to get offers from a specific agent with role “SB” and run 10 tasks (i give also to my Framework role “SB”), then i store those information (which are actually TaskInfo in Schedulers TreeMap). After that i would like to change the role of my Framework to “*(default)”. Then i will get offer from an agent that has the default role and i will still have the info in my TreeMap because scheduler instance didn’t stop. That’s all. My problem is that i don’t know how to change the role of the Framework without losing that TreeMap, and also how to set it with version 1.3.0. Hope that everybody understands now….
