Hello, I want to execute tasks which requires some other tasks from other framework(s) already running. I'm thinking where such logic/strategy/policy belongs in principle. I understand scheduling as a process to decide where to execute task according to some resources availability, typically CPU, mem, net, hdd etc.
If my task require other tasks running could I generalize and consider that those tasks from other frameworks are kind of required resources and put this logic/strategy decisions into scheduler? Like if I want to run my task collocated with some other tasks on the same node I have to make this decision somewhere. Does it make any sense? I'm asking because I have never thought about other frameworks/tasks as "resources" so that I could put them into scheduler to satisfy my understanding of a scheduler. Or it rather belongs higher like to a framework, or lower to an executor? Should scheduler be dedicated to decisions about resources which are offered and am I mixing concepts? Or I just should keep distinction between resources and requirements/policies or whatever but anyway does this kind of logic still belongs to scheduler or it should be somewhere else? I'm trying to understand which logic should be in scheduler and what should go somewhere else. Many thanks, Petr
