Examples of org.apache.hadoop.mapreduce.SleepJob

org.apache.hadoop.mapreduce.SleepJob
Dummy class for testing MR framefork. Sleeps for a defined period of time in mapper and reducer. Generates fake input for map / reduce jobs. Note that generated number of input pairs is in the order of numMappers * mapSleepTime / 100, so the job uses some disk space.
