> Reporter: Kyle Nusbaum

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