示例1: testSleepJobInternal

import org.apache.hadoop.mapreduce.Job; //導入方法依賴的package包/類
private void testSleepJobInternal(boolean useRemoteJar) throws Exception {
  LOG.info("\n\n\nStarting testSleepJob: useRemoteJar=" + useRemoteJar);

  if (!(new File(MiniMRYarnCluster.APPJAR)).exists()) {
    LOG.info("MRAppJar " + MiniMRYarnCluster.APPJAR
             + " not found. Not running test.");
    return;
  }

  Configuration sleepConf = new Configuration(mrCluster.getConfig());
  // set master address to local to test that local mode applied iff framework == local
  sleepConf.set(MRConfig.MASTER_ADDRESS, "local");	
  
  SleepJob sleepJob = new SleepJob();
  sleepJob.setConf(sleepConf);
 
  // job with 3 maps (10s) and numReduces reduces (5s), 1 "record" each:
  Job job = sleepJob.createJob(3, numSleepReducers, 10000, 1, 5000, 1);

  job.addFileToClassPath(APP_JAR); // The AppMaster jar itself.
  if (useRemoteJar) {
    final Path localJar = new Path(
        ClassUtil.findContainingJar(SleepJob.class));
    ConfigUtil.addLink(job.getConfiguration(), "/jobjars",
        localFs.makeQualified(localJar.getParent()).toUri());
    job.setJar("viewfs:///jobjars/" + localJar.getName());
  } else {
    job.setJarByClass(SleepJob.class);
  }
  job.setMaxMapAttempts(1); // speed up failures
  job.submit();
  String trackingUrl = job.getTrackingURL();
  String jobId = job.getJobID().toString();
  boolean succeeded = job.waitForCompletion(true);
  Assert.assertTrue(succeeded);
  Assert.assertEquals(JobStatus.State.SUCCEEDED, job.getJobState());
  Assert.assertTrue("Tracking URL was " + trackingUrl +
                    " but didn't Match Job ID " + jobId ,
        trackingUrl.endsWith(jobId.substring(jobId.lastIndexOf("_")) + "/"));
  verifySleepJobCounters(job);
  verifyTaskProgress(job);
  
  // TODO later:  add explicit "isUber()" checks of some sort (extend
  // JobStatus?)--compare against MRJobConfig.JOB_UBERTASK_ENABLE value

         + " not found. Not running test.");
    return;
  }

  Path first = createTempFile("distributed.first", "x");
  // Create two jars with a single file inside them.
  Path second =
      makeJar(new Path(TEST_ROOT_DIR, "distributed.second.jar"), 2);
  Path third =
      makeJar(new Path(TEST_ROOT_DIR, "distributed.third.jar"), 3);
  Path fourth =
      makeJar(new Path(TEST_ROOT_DIR, "distributed.fourth.jar"), 4);

  Job job = Job.getInstance(mrCluster.getConfig());
  
  // Set the job jar to a new "dummy" jar so we can check that its extracted 
  // properly
  job.setJar(jobJarPath);
  // Because the job jar is a "dummy" jar, we need to include the jar with
  // DistributedCacheChecker or it won't be able to find it
  Path distributedCacheCheckerJar = new Path(
          JarFinder.getJar(DistributedCacheChecker.class));
  job.addFileToClassPath(distributedCacheCheckerJar.makeQualified(
          localFs.getUri(), distributedCacheCheckerJar.getParent()));
  
  job.setMapperClass(DistributedCacheChecker.class);
