Hadoop基础---MapReduce及YARN中job提交源码分析（进一步理解Hadoop机制）

补充：下载Hadoop源码

一：YARN框架：进行资源调度

（一）YARN框架流程图

注意：yarn框架只做资源的管理，如果要运行一个程序，则会为该程序分配节点、内存、cpu等资源，至于该程序如何运行，yarn框架不进行管理。故也不会知道mapreduce的运行逻辑 。同样因为这样的松耦合，yarn框架的使用范围更加广泛，可以兼容其他运行程序。

补充：MapReduce框架知道我们写的map-reduce程序的运行逻辑。我们写的map-reduce中并没有管理层的任务运行分配逻辑，该逻辑被封装在MapReduce框架里面，被封装为MRAppMaster类，该类用于管理整个map-reduce的运行逻辑。（map-reduce程序的管理者）

重点：步骤6中，由NodeManager主动发送心跳包，去ResourceManager检测是否有job任务，只当该NodeManager（即DataNode）有相关资源时，才会领取该job

MRAppMaster由YARN框架启动（动态启动，随机选取）

（二）补充：RunJar上传到HDFS中的资源:

1.其中job.jar就是我们生成的wc.jar包。

2.job.split中数据如下：

SPL/org.apache.hadoop.mapreduce.lib.input.FileSplit(hdfs://hadoopH1:9000/wc/input/wcdata.txt;

含有输入数据所在HDFS路径及文件名。

3.job.splitmetainfo数据如下：

META-SPhadoopH1;

为节点主机名。

4.job.xml含有集群的各种配置信息

job.xml

二：MapReduce框架 （结合YARN框架）

补充：MapReduce框架知道我们写的map-reduce程序的运行逻辑。我们写的map-reduce中并没有管理层的任务运行分配逻辑，该逻辑被封装在MapReduce框架里面，被封装为MRAppMaster类，该类用于管理整个map-reduce的运行逻辑。（map-reduce程序的管理者）

MRAppMaster由YARN框架启动（动态启动，随机选取）

（一）框架流程图

注：MRAppMaster和yarnChild(包括map task和reduce task)都是动态产生的。

三： Job提交源码分析

（一）客户端提交job

wcjob.waitForCompletion(true);//将job提交给集群运行

（二）job.java进行提交

  public boolean waitForCompletion(boolean verbose
                                   ){
    if (state == JobState.DEFINE) {
      submit();　　//进行提交
    }
    if (verbose) {
      monitorAndPrintJob(); //监视并打印job状态
    } else {
      // get the completion poll interval from the client.
      int completionPollIntervalMillis = 
        Job.getCompletionPollInterval(cluster.getConf());
      while (!isComplete()) {
        try {
          Thread.sleep(completionPollIntervalMillis);
        } catch (InterruptedException ie) {
        }
      }
    }
    return isSuccessful();　　//返回成功状态
  }

（三）job提交信息到集群中

  public void submit(){
    ensureState(JobState.DEFINE);　　//再确认一遍状态
    setUseNewAPI();　　//使用新的API
    connect();　　
    final JobSubmitter submitter = 
        getJobSubmitter(cluster.getFileSystem(), cluster.getClient());
    status = ugi.doAs(new PrivilegedExceptionAction<JobStatus>() {
      public JobStatus run() throws IOException, InterruptedException, 
      ClassNotFoundException {
        return submitter.submitJobInternal(Job.this, cluster);
      }
    });
    state = JobState.RUNNING;
    LOG.info("The url to track the job: " + getTrackingURL());
   }

（四）job.class中connect为集群赋值

  private synchronized void connect()
          throws IOException, InterruptedException, ClassNotFoundException {
    if (cluster == null) {
      cluster = 
        ugi.doAs(new PrivilegedExceptionAction<Cluster>() {
                   public Cluster run()
                          throws IOException, InterruptedException, 
                                 ClassNotFoundException {
                     return new Cluster(getConfiguration());
                   }
                 });
    }
  }

（五）Cluster.class中集群的赋值

  public Cluster(Configuration conf) throws IOException {
    this(null, conf);
  }

  public Cluster(InetSocketAddress jobTrackAddr, Configuration conf) 
      throws IOException {
    this.conf = conf;　　//配置信息
    this.ugi = UserGroupInformation.getCurrentUser();　　//当前用户
    initialize(jobTrackAddr, conf);
  }

（六）集群初始化

 private void initialize(InetSocketAddress jobTrackAddr, Configuration conf)
      throws IOException {

    synchronized (frameworkLoader) {
      for (ClientProtocolProvider provider : frameworkLoader) {　　//循环所有框架，直到成功创建一个为止
        ClientProtocol clientProtocol = null; 
        try {
          if (jobTrackAddr == null) {
            clientProtocol = provider.create(conf);
          } else {
            clientProtocol = provider.create(jobTrackAddr, conf);
          }

          if (clientProtocol != null) {
            clientProtocolProvider = provider;
            client = clientProtocol;
            LOG.debug("Picked " + provider.getClass().getName()
                + " as the ClientProtocolProvider");
            break;
          }
          else {
            LOG.debug("Cannot pick " + provider.getClass().getName()
                + " as the ClientProtocolProvider - returned null protocol");
          }
        } 
        catch (Exception e) {
          LOG.info("Failed to use " + provider.getClass().getName()
              + " due to error: " + e.getMessage());
        }
      }
    }

    if (null == clientProtocolProvider || null == client) {
      throw new IOException(
          "Cannot initialize Cluster. Please check your configuration for "
              + MRConfig.FRAMEWORK_NAME
              + " and the correspond server addresses.");
    }
  }

1.集群客户端创建

（1）本地创建

public class LocalClientProtocolProvider extends ClientProtocolProvider {

  @Override
  public ClientProtocol create(Configuration conf) throws IOException {
    String framework =
        conf.get(MRConfig.FRAMEWORK_NAME, MRConfig.LOCAL_FRAMEWORK_NAME);
    if (!MRConfig.LOCAL_FRAMEWORK_NAME.equals(framework)) {
      return null;
    }
    conf.setInt(JobContext.NUM_MAPS, 1);

    return new LocalJobRunner(conf);
  }

获取配置信息，可以知道框架使用yarn

可以知道两者不等，故不创建本地集群客户端！！！

（2）.创建yarn集群客户端

public class YarnClientProtocolProvider extends ClientProtocolProvider {

  @Override
  public ClientProtocol create(Configuration conf) throws IOException {
    if (MRConfig.YARN_FRAMEWORK_NAME.equals(conf.get(MRConfig.FRAMEWORK_NAME))) {
      return new YARNRunner(conf);
    }

集群客户端获取成功

          if (clientProtocol != null) {
            clientProtocolProvider = provider;　　//为成员变量赋值
            client = clientProtocol;
            LOG.debug("Picked " + provider.getClass().getName()
                + " as the ClientProtocolProvider");
            break;　　//退出循环，不再创建集群
          }

（七）立即提交job到集群中去

  JobStatus submitJobInternal(Job job, Cluster cluster){
    Path jobStagingArea = JobSubmissionFiles.getStagingDir(cluster, conf);　　//从ResourceManager中获取资源配置存放路径
    JobID jobId = submitClient.getNewJobID();　　//获取jobid，用于创建目录
    job.setJobID(jobId);
    Path submitJobDir = new Path(jobStagingArea, jobId.toString());　　//生成完整路径
    JobStatus status = null;
    try {
      
      copyAndConfigureFiles(job, submitJobDir);　　//提交jar包和配置文件到资源hdfs配置路径
int maps = writeSplits(job, submitJobDir);　　//获取切片信息
// Write job file to submit dir
      writeConf(conf, submitJobFile);　　//写描述文件xml到hdfs配置路径
    }
  }

完整资源配置路径：
