    What is the purpose of RecordReader in Hadoop?

    The InputSplit has defined a slice of work, but does not describe how to access it. The RecordReader class actually loads the data from1 its source and converts it into (key, value) pairs suitable for reading by the Mapper. The RecordReader instance is defined by the Input Format.
