mapResultToRecord

public void mapResultToRecord(Record record,
                              HBaseKey key,
                              HBaseResult result)

Description copied from class: TableInputFormat

Maps the current HBase Result into a Record. This implementation simply stores the HBaseKey at position 0, and the HBase Result object at position 1.

Overrides:
