-------------------------------
Fix Version/s: (was: 1.2.0)
> ZooKeeper-Based Service Discovery
> ---------------------------------
>
> Key: KNOX-1015
> URL: https://issues.apache.org/jira/browse/KNOX-1015
> Project: Apache Knox
> Issue Type: Improvement
> Components: Server
> Affects Versions: 0.14.0
> Reporter: Phil Zampino
> Priority: Major
> Labels: kip-8
>
> 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.
