    • [MUMAK] Randomize the arrival of heartbeat responses

    Description

      We propose to make the following changes to mumak, MAPREDUCE-728

      • make the timing of heartbeat responses more realistic by adding an option to randomly perturb them
      • randomize the startup time of task trackers in a fixed interval
      • remove 2 magic constants from SimulatorEngine and make sure that the first job is submitted only after the entire cluster is up and running
