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：
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。

}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/";

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");
