类 MasterTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>

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

类型参数：

MASTER_RESULT - master computation result in each iteration.

WORKER_RESULT - worker computation result in each iteration.

所有已实现的接口：

MasterInterceptor<MASTER_RESULT,WORKER_RESULT>

public class MasterTimer<MASTER_RESULT extends Bytable,WORKER_RESULT extends Bytable>
extends Object
implements MasterInterceptor<MASTER_RESULT,WORKER_RESULT>

MasterTimer is used to get execution time of the post intercepters and master computation. This time includes waiting time and should be set in system intercepters.

MasterTimer()

方法摘要

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