类 MemoryStatsWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

java.lang.Object
  ml.shifu.guagua.worker.BasicWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>
      ml.shifu.guagua.worker.MemoryStatsWorkerInterceptor<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 MemoryStatsWorkerInterceptor<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends BasicWorkerInterceptor<MASTER_RESULT,WORKER_RESULT>

MemoryStatsWorkerInterceptor is used to print memory usage for each worker checkpoint.

MemoryStatsWorkerInterceptor()

方法摘要

void	postApplication(WorkerContext<MASTER_RESULT,WORKER_RESULT> context) The hook point for each application or each mapreduce job which is after all iterations completed.
void	postIteration(WorkerContext<MASTER_RESULT,WORKER_RESULT> context) The hook point for each iteration which is after WorkerComputable.compute(WorkerContext).
void	preApplication(WorkerContext<MASTER_RESULT,WORKER_RESULT> context) The hook point for each application or each mapreduce job which is before all iterations started.
void	preIteration(WorkerContext<MASTER_RESULT,WORKER_RESULT> context) The hook point for each iteration which is before WorkerComputable.compute(WorkerContext).
