ReduceAttemptFinishedEvent

public ReduceAttemptFinishedEvent(TaskAttemptID id,
                                  TaskType taskType,
                                  String taskStatus,
                                  long shuffleFinishTime,

                                  long finishTime,
                                  String hostname,
                                  int port,
                                  String rackName,
                                  String state,
                                  Counters counters,
                                  int[][] allSplits)

Create an event to record completion of a reduce attempt

Parameters:

id - Attempt Id

taskType - Type of task

taskStatus - Status of the task

shuffleFinishTime - Finish time of the shuffle phase

sortFinishTime - Finish time of the sort phase

finishTime - Finish time of the attempt

hostname - Name of the host where the attempt executed

port - RPC port for the tracker host.

rackName - Name of the rack where the attempt executed

state - State of the attempt

counters - Counters for the attempt

allSplits - the "splits", or a pixelated graph of various measurable worker node state variables against progress. Currently there are four; wallclock time, CPU time, virtual memory and physical memory.
