Description

As part of HADOOP-17835 (replacing PathChildrenCache/TreeCache by CuratorCache), realized that although registerPathListener() of CuratorService returns ListenerHandle, it is not used by RegistryDNSServer. We can remove ListenerHandle from hadoop-registry as it is not Public/LP interface.
