Assignee: (was: Stephen O'Donnell)
> Create service catalog endpoint in the SCM
> ------------------------------------------
>
> Key: HDDS-1743
> URL: https://issues.apache.org/jira/browse/HDDS-1743
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: SCM
> Reporter: Marton Elek
> Priority: Major
>
> Based on the the design doc in the parent pom, we need a Service Catalog
> endpoint in the SCM.
>
> {code:java}
> public interface ServiceRegistry {
> void register(ServiceEndpoint endpoint) throws IOException;
> ServiceEndpoint findEndpoint(String serviceName, int instanceId);
> Collection<ServiceEndpoint> getAllServices();
> }{code}
> Where the ServiceEndpoint is something like this:
> {code:java}
> public class ServiceEndpoint {
> private String host;
> private String ip;
> private ServicePort port;
> private String serviceName;
> private int instanceId;
> ...
> }
> public class ServicePort {
>
> private ServiceProtocol protocol;
> private String name;
> private int port;
> ...
> }
> public enum ServiceProtocol {
> RPC, HTTP, GRPC
> }{code}
> The ServiceRegistry may have multiple implementation, but as a first step we
> need a simple implementation which calls a new endpoint on SCM via REST.
> The endpoint should persist the data to a local Rocksdb with the help of
> DBStore.
> This task is about to create the server and client implementation. In a
> follow-up Jira we can start to use the client on the om/datanode/client side
> to mix the service discovery data with the existing configuration.
