> 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.
