Enclosing class:

PerformanceEvaluation

public static class PerformanceEvaluation.PeInputSplit
extends org.apache.hadoop.mapreduce.InputSplit
implements org.apache.hadoop.io.Writable

This class works as the InputSplit of Performance Evaluation MapReduce InputFormat, and the Record Value of RecordReader. Each map task will only read one record from a PeInputSplit, the record value is the PeInputSplit itself.
