类 MemoryCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object
  ml.shifu.guagua.MemoryCoordinator<MASTER_RESULT,WORKER_RESULT>

类型参数：

MASTER_RESULT - master computation result in each iteration.

WORKER_RESULT - worker computation result in each iteration.

public class MemoryCoordinator<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends Object

MemoryCoordinator is helper for in-memory master and worker coordination.

Master result can be set from master by signalWorkers(int, Bytable). Workers can get the result by getMasterResult().

Worker results can be set from worker by signalWorkers(int, Bytable). Master can get the result by getWorkerResults().
