类 LocalMasterCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object
  ml.shifu.guagua.master.BasicMasterInterceptor<MASTER_RESULT,WORKER_RESULT>
      ml.shifu.guagua.master.LocalMasterCoordinator<MASTER_RESULT,WORKER_RESULT>

类型参数：

MASTER_RESULT - master result for computation in each iteration.

WORKER_RESULT - worker result for computation in each iteration.

所有已实现的接口：

MasterInterceptor<MASTER_RESULT,WORKER_RESULT>

public class LocalMasterCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends BasicMasterInterceptor<MASTER_RESULT,WORKER_RESULT>

LocalMasterCoordinator is local coordinator implementation in one jvm instance.

LocalMasterCoordinator is a proxy and coordinator has the real logic to coordinate master and workers. coordinator should be set by using the same instance with InternalWorkerCoordinator.
