> Implement service discovery where ZooKeeper is the service registry.
> Discover the appropriate URLs to declare in the Knox topology for the services specified in the simple topology descriptor.
> Need to determine to what degree Hadoop services are registering their details in ZooKeeper, and may need to encourage them to do so or augment what they're already registering.
> This must be named something less generic than "ZooKeeper" Service Discovery, since the implementation will depend on the structure of the data registered by the services, and will not be a general-purpose ZooKeeper service discovery mechanism.
> Here is a link to the existing YARN Service Registry docs - we will need to determine whether there is enough fidelity in the metadata available there to actual generate topologies from it. https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/registry/yarn-registry.html
