Hello everbody, I am wondering if there is a feature allowing (in my case) reduce tasks to communicate. For example by some volatile variables at some centralized point. Or maybe just notify other running or to-be-running reduce tasks of a completed reduce task featuring some arguments.
In my case, I have reduce tasks doing computations that will output/produce certain quality threshold. Other reduce tasks can/could estimate, if they ever get above those thresholds. If not they could just cease running. Thanks in advance, Martin PS: If such functions are not yet part of the API, I would like to know if there are good reasons for it and if not, propose to introduce such functionality.
