To work appropriately, Map Reduce needs some design parameters to be set accurately. Without them set accurately, the map and reduce jobs won’t work appropriately. The configuration parameters that should be set effectively are as per the following:
  • Job’s input area in HDFS.
  • Job’s output area in HDFS.
  • Input and Output format.
  • Classes that contain the map and decrease capacities.
  • Lastly jar file for reducer, mapper and driver classes.
