通过AWS Java SDK设置EMR

以下是我设置EMR群集的代码：

public void createCluster(){
        AWSCredentials credentials = new BasicAWSCredentials("xxx","xxx");
        AmazonElasticMapReduceClient emr = new AmazonElasticMapReduceClient(credentials);

        StepFactory stepFactory = new StepFactory();

        StepConfig enableDebugging = new StepConfig()
            .withName("Enable Debugging")
            .withActionOnFailure("TERMINATE_JOB_FLOW")
            .withHadoopJarStep(stepFactory.newEnableDebuggingStep());

        StepConfig installHive = new StepConfig()
            .withName("Install Hive")
            .withActionOnFailure("TERMINATE_JOB_FLOW")
            .withHadoopJarStep(stepFactory.newInstallHiveStep());

       /* StepConfig hiveScript = new StepConfig().withName("Hive Script")
            .withActionOnFailure("TERMINATE_JOB_FLOW")
            .withHadoopJarStep(stepFactory.newRunHiveScriptStep("s3://mywordcountbuckett/binary/WordCount.jar"));
            */

        RunJobFlowRequest request = new RunJobFlowRequest()
            .withName("Hive Interactive")
            .withAmiVersion("3.8")
            .withSteps(enableDebugging, installHive)

            .withLogUri("s3://mywordcountbuckett/")
            .withServiceRole("EMR_DefaultRole")
            .withJobFlowRole("EMR_EC2_DefaultRole")
            .withInstances(new JobFlowInstancesConfig()
                .withEc2KeyName("mykeypair")
                .withInstanceCount(5)
                .withKeepJobFlowAliveWhenNoSteps(true)
                .withMasterInstanceType("m3.xlarge")
                .withSlaveInstanceType("m1.large"));

        RunJobFlowResult result = emr.runJobFlow(request);
        System.out.println("This is result: " + result.toString());

println打印出以下内容：

This is result: {JobFlowId: j-10BX80MGWF3XQ}

这是否意味着我已成功创建集群？然而，当我试图从aws.amazon.com查看时，没有创建任何集群

EC2中也没有创建任何内容。

这是区域问题

放置此代码，所有操作都相应进行：

emr.setRegion(Region.getRegion(Regions.US_WEST_2));

从控制台看，您是在看正确的区域吗？从控制台看，您是在看正确的区域吗？
