> * *_LeaderElectionService_*
> * Contends for the leadership of a service in JobManager. There are four
> components in a JobManager instance that use LeaderElectionService:
> ResourceManager, Dispatcher, JobManager, RestEndpoint(aka WebMonitor).
> * Once the leader election is finished, the active leader addresses will be
> stored in the ConfigMap so that other components could retrieve successfully.
> * *_LeaderRetrievalService_*
> * Used by Client to get the RestEndpoint address for the job submission.
> * Used by JobManager to get the ResourceManager address for registration.
> * Used by TaskManagers to retrieve addresses of the corresponding
> LeaderElectionService(e.g. JobManager address, ResourceManager address) for
> registration and offering slots
