Flink任务、Spark任务提交到集群,通常需要将可执行Jar上传到集群,手动执行任务提交指令,如果有配套的大数据平台则需要上传Jar,由调度系统进行任务提交。 对开发者来说,本地IDEA调试Flink、Spark任务不涉及对象的序列化及反序列化,任务在本地调试通过后,执行在分布式环境下也可能会出错。 而将任务提交到集群进行调试还要走那些繁琐的流程太影响效率了。

因此,为方便大数据开发人员进行快速开发调试,开发了从本地IDEA提交Flink/Spark任务到集群的工具类。任务提交代码稍加改造后也可以和上层调度系统进行集成,替代脚本模式进行任务提交的方式。

  • 支持Flink yarnPerJob模式下的任务提交。

  • 支持Spark任务以Yarn Cluster模式提交到YARN,支持自动上传用户Jar包,依赖的Spark Jars需要提前上传到HDFS。

  • 支持Spark任务提交到K8s Cluster,执行的jar需要包含在镜像中,任务执行时需要传递镜像名称及可执行文件路径。如果需要操作hive表,则需要传递集群所在文件夹,以及HADOOP_USER_NAME,系统进行Hadoop文件的挂载及环境变量的设置。

任务类型提交入口类:

Spark-Yarn-Submit-Client

Spark-K8s-Submit-Client

Flink-Yarn-Submit-Client

Flink 多执行模式任务提交

  • 需要填写Flink任务运行时参数配置,任务运行所在的集群配置路径,本地Flink根路径。项目依赖flink1.10版本。
  • 支持以YarnSession、YarnPerjob、Standalone模式进行任务提交,返回ApplicationId。
  • example模块下包含一个FlinkDemo,打包后会转移到项目的examplJars中,可以尝试进行任务提交。
  • 任务提交后,根据ApplicationId获取任务执行使用的jm、tm日志基本信息,包含日志访问URL,日志总字节大小,根据日志基本信息可以做日志滚动展示,防止Yarn日志过大导致日志读取卡死。
  • 提供任务取消、任务状态获取、已完成任务日志获取接口。

V2版本增加flink-yarn-submiter-service,用来做多版本的隔离。新版本任务执行的入口类为 ClusterClient。

任务操作示例:

   public static JobParamsInfo buildJobParamsInfo() {

       //        System.setProperty("java.security.krb5.conf", "/Users/maqi/tmp/hadoopconf/cdh514/krb5.conf");

       // job submit

       // running log info
       appIdAndJobId.ifPresent((pair) -> printRollingLogBaseInfo(jobParamsInfo, pair));

       // cancel job

Spark on yarn 任务提交

  • 填写用户程序包路径、执行参数、集群配置文件夹、安全认证等相关配置。
  • Spark任务提交使用Yarn cluster模式,使用的Spark Jar需要提前上传到HDFS并作为archive的参数。
  • 针对SparkSQL任务,通过提交examples中的spark-sql-proxy程序包来直接操作hive表。

提交示例:

public static void main(String[] args) throws Exception {
        boolean openKerberos = true;
        String appName = "todd spark submit";
        String runJarPath = "/Users/maqi/code/ClustersSubmiter/exampleJars/spark-sql-proxy/spark-sql-proxy.jar";
        String mainClass = "cn.todd.spark.SparksqlProxy";
        String yarnConfDir = "/Users/maqi/tmp/hadoopconf";
        String principal = "hdfs/[email protected]";
        String keyTab = "/Users/maqi/tmp/hadoopconf/hdfs.keytab";
        String jarHdfsDir = "sparkproxy2";
        String archive = "hdfs://nameservice1/sparkjars/jars";
        String queue = "root.users.hdfs";
        String execArgs = getExampleJobParams();

        Properties confProperties = new Properties();
        confProperties.setProperty("spark.executor.cores","2");

        JobParamsInfo jobParamsInfo = JobParamsInfo.builder()
                .setAppName(appName)
                .setRunJarPath(runJarPath)
                .setMainClass(mainClass)
                .setYarnConfDir(yarnConfDir)
                .setPrincipal(principal)
                .setKeytab(keyTab)
                .setJarHdfsDir(jarHdfsDir)
                .setArchivePath(archive)
                .setQueue(queue)
                .setExecArgs(execArgs)
                .setConfProperties(confProperties)
                .setOpenKerberos(BooleanUtils.toString(openKerberos, "true", "false"))
                .build();

        YarnConfiguration yarnConf = YarnConfLoaderUtil.getYarnConf(yarnConfDir);
        String applicationId = "";

        if (BooleanUtils.toBoolean(openKerberos)) {
            UserGroupInformation.setConfiguration(yarnConf);
            UserGroupInformation userGroupInformation = UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, keyTab);
            applicationId = userGroupInformation.doAs((PrivilegedExceptionAction<String>) () -> LauncherMain.run(jobParamsInfo, yarnConf));
        } else {
            LauncherMain.run(jobParamsInfo, yarnConf);
        }

        System.out.println(applicationId);
    }

Spark on k8s 任务提交

  • 基于Spark2.4.4进行开发,通过将spark-sql-proxy.jar包打入镜像来执行Sparksql并操作Hive表,无其他特殊操作。
  • 操作Hive时需要传递hadoopConfDir,程序会自动将.xml文件内容进行挂载,如果非root用户操作Hive,需要设置HADOOP_USER_NAME。
  • 通过读取kubeConfig配置文件进行Kuberclient的创建,而非官方提供的master url方式。
  • 任务提交后立即返回spark-app-selector id,从而进行POD状态获取。
  public static void main(String[] args) throws Exception {
      String appName = "todd spark submit";
      // 镜像内的jar路径
      String runJarPath = "local:///opt/dtstack/spark/spark-sql-proxy.jar";
      String mainClass = "cn.todd.spark.SparksqlProxy";
      String hadoopConfDir = "/Users/maqi/tmp/hadoopconf/";
      String kubeConfig = "/Users/maqi/tmp/conf/k8s.config";
      String imageName = "mqspark:2.4.4";
      String execArgs = getExampleJobParams();

      Properties confProperties = new Properties();
      confProperties.setProperty("spark.executor.instances", "2");
      confProperties.setProperty("spark.kubernetes.namespace", "default");
      confProperties.setProperty("spark.kubernetes.authenticate.driver.serviceAccountName", "spark");
      confProperties.setProperty("spark.kubernetes.container.image.pullPolicy", "IfNotPresent");


      JobParamsInfo jobParamsInfo = JobParamsInfo.builder()
              .setAppName(appName)
              .setRunJarPath(runJarPath)
              .setMainClass(mainClass)
              .setExecArgs(execArgs)
              .setConfProperties(confProperties)
              .setHadoopConfDir(hadoopConfDir)
              .setKubeConfig(kubeConfig)
              .setImageName(imageName)
              .build();

      String id = run(jobParamsInfo);
      System.out.println(id);
  }
