| Class Summary | |
|---|---|
| SecondarySort | An example MapReduce job showing how the Tuple and ShuffleUtils can be used in conjunction with
each other to secondary sort people's names. |
| SecondarySort.Map | This map class simply tokenizes each input line, and emits a (tuple, line) pair, where the tuple contains the last and first name. |
| SecondarySort.Reduce | The reducer just emits the map output values, allowing us to examine the resulting output and determine the results of the secondary sort. |
