ml.shifu.guagua.worker
类 InternalWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object
  ml.shifu.guagua.worker.BasicWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>
      ml.shifu.guagua.worker.InternalWorkerCoordinator<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：

WorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

public class InternalWorkerCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends BasicWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

InternalWorkerCoordinator is local coordinator implementation on one jvm instance.

coordinator should be set by using the same instance with InternalMasterCoordinator.
