Flink 本地启动的多种方式

在这里插入图片描述

Application模式通过代码提交到Yarn上启动

//设置Yarn客户端
YarnClient yarnClient = ;
Configuration configuration = new Configuration();
if (customConfiguration != null) {
  configuration.addAll(customConfiguration);
}
configuration.set(JobManagerOptions.TOTAL_PROCESS_MEMORY, MemorySize.parse("1024m"));
configuration.set(TaskManagerOptions.TOTAL_PROCESS_MEMORY, MemorySize.parse("1024m"));
configuration.set(DeploymentOptions.TARGET, YarnDeploymentTarget.APPLICATION.getName());
// 设置flink-dist-???.jar
String distPath = ;
configuration.set(YarnConfigOptions.FLINK_DIST_JAR, distPath);
// 设置需要执行的jar包
String examplePath = ;
configuration.set(PipelineOptions.JARS, Collections.singletonList(examplePath));
FileSystem fileSystem = FileSystem.get(hadoopClusterTest.getConfig());
//设置flink lib
String dirPath = ;
// 上传flink libjar包到hdfs中
fileSystem.copyFromLocalFile(new Path(dirPath), new Path(dirPath));
configuration.set(YarnConfigOptions.PROVIDED_LIB_DIRS, Collections.singletonList(dirPath));
setIfAbsent(configuration, PipelineOptions.JARS, new ArrayList<>());
YarnConfiguration yarnConfiguration = new YarnConfiguration();
YarnClientYarnClusterInformationRetriever yarnClientYarnClusterInformationRetriever =
  YarnClientYarnClusterInformationRetriever.create(yarnClient);
YarnClusterDescriptor yarnClusterDescriptor = new YarnClusterDescriptor(
  configuration,
  yarnConfiguration,
  yarnClient,
  yarnClientYarnClusterInformationRetriever,
  true
);
ClusterSpecification clusterSpecification = new ClusterSpecification
  .ClusterSpecificationBuilder()
  .setSlotsPerTaskManager(1)
  .createClusterSpecification();

ApplicationConfiguration applicationConfiguration = new ApplicationConfiguration(
  new String[]{},
  // 需要执行的类全名
);
try {
  // 启动ApplicationCluster
  yarnClusterDescriptor.deployApplicationCluster(clusterSpecification, applicationConfiguration);
} catch (ClusterDeploymentException e) {
  e.printStackTrace();
}

Session模式通过代码提交到Yarn上启动

public class YarnFlinkSessionTest {
    ClusterClient<ApplicationId> clusterClient;
    @Test
    void test() throws ExecutionException, InterruptedException {
        YarnClient yarnClient = //创建Yarn客户端
        Configuration configuration = new Configuration();
        configuration.set(JobManagerOptions.TOTAL_PROCESS_MEMORY,
            MemorySize.parse("1024m"));
        configuration.set(TaskManagerOptions.TOTAL_PROCESS_MEMORY,
            MemorySize.parse("1024m"));
        configuration.set(YarnConfigOptions.FLINK_DIST_JAR, "${FLINK_HOME}/lib/flink-dist-1.16.2.jar");
        YarnConfiguration yarnConfiguration = new YarnConfiguration();
        YarnClientYarnClusterInformationRetriever yarnClientYarnClusterInformationRetriever =
            YarnClientYarnClusterInformationRetriever.create(yarnClient);
        YarnClusterDescriptor yarnClusterDescriptor = new YarnClusterDescriptor(
            configuration,
            yarnConfiguration,
            yarnClient,
            yarnClientYarnClusterInformationRetriever,
            true
        );
        ClusterSpecification clusterSpecification = new ClusterSpecification.ClusterSpecificationBuilder()
            .setMasterMemoryMB(1024)
            .setTaskManagerMemoryMB(1024)
            .setSlotsPerTaskManager(1)
            .createClusterSpecification();
        try {
            ClusterClientProvider<ApplicationId> applicationIdClusterClientProvider = yarnClusterDescriptor.deploySessionCluster(clusterSpecification);
            clusterClient = applicationIdClusterClientProvider.getClusterClient();
        } catch (ClusterDeploymentException e) {
            e.printStackTrace();
        }
        Thread.sleep(10000000);
    }
}
