Subject [jira] [Created] (HDFS-12868) Ozone: Service Discovery API

----------------------------------

             Summary: Ozone: Service Discovery API
                 Key: HDFS-12868
                 URL: https://issues.apache.org/jira/browse/HDFS-12868
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
            Reporter: Nanda kumar
            Assignee: Nanda kumar


Currently if a client wants to connect to Ozone cluster we need multiple properties to be
configured in the client.

For RPC based connection we need
{{ozone.ksm.address}}
{{ozone.scm.client.address}}
and the ports if something other than default is configured.

For REST based connection
{{ozone.rest.servers}}
and port if something other than default is configured.

With the introduction of Service Discovery API the client should be able to discover all the
configurations needed for the connection. Service discovery calls will be handled by KSM,
at the client side, we only need to configure {{ozone.ksm.address}}. The client should first
connect to KSM and get all the required configurations.
