> Periodically the supervisors and workers each download their assignments from zookeeper, and the traffic begins to saturate the network and hammer zookeeper as we scale. Having these daemons only grab the assignments when the zookeeper path's version number changes reduces this traffic considerably, along with STORM-376.
