Examples of org.apache.hadoop.examples.SleepJob

org.apache.hadoop.examples.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.

    // No map-memory configuration
    JobConf jobConf = new JobConf(clusterConf);
    String[] args = { "-m", "0", "-r", "0", "-mt", "0", "-rt", "0" };
    String msg = null;
    try {
      ToolRunner.run(jobConf, new SleepJob(), args);
      assertTrue(false);
    } catch (RemoteException re) {
      System.out.println("Exception " + StringUtils.stringifyException(re));
