Java Apache Beam:未能序列化和反序列化属性'；awsCredentialsProvider&x27；

我从

https://github.com/apache/beam

。我正在做一个更改，以便它可以作为接收器写入AWS S3。在我的第一次迭代中，我能够使用以下代码使其工作

    public static void main(String[] args) {
        Options options = PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);

        options.setAwsCredentialsProvider(
                new AWSStaticCredentialsProvider(
                        new BasicAWSCredentials(options.getAwsAccessKey().get(), options.getAwsSecretKey().get())));

        runBigQueryTornadoes(options);
    }

    public static void main(String[] args) {
        Options options = PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);

        AWSCredentialsProvider provider = new AWSStaticCredentialsProvider(new BasicAWSCredentials(options.getAwsAccessKey().get(), options.getAwsSecretKey().get()));
        AWSSecurityTokenServiceClientBuilder stsBuilder = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(provider);
        AWSSecurityTokenService sts = stsBuilder.build();

        AWSCredentialsProvider credentialsProvider = new STSAssumeRoleSessionCredentialsProvider.Builder(options.getAwsRoleArn().get(), options.getAwsRoleSession().get())
                .withExternalId(options.getAwsExternalId().get())
                .withStsClient(sts)
                .build();
        options.setAwsCredentialsProvider(credentialsProvider);

        runBigQueryTornadoes(options);
    }

在我的第二次迭代中，我希望使用

STSAssumeRoleSessionCredentialsProvider

来支持跨帐户IAM角色。我有以下代码

    public static void main(String[] args) {
        Options options = PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);

        options.setAwsCredentialsProvider(
                new AWSStaticCredentialsProvider(
                        new BasicAWSCredentials(options.getAwsAccessKey().get(), options.getAwsSecretKey().get())));

        runBigQueryTornadoes(options);
    }

    public static void main(String[] args) {
        Options options = PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);

        AWSCredentialsProvider provider = new AWSStaticCredentialsProvider(new BasicAWSCredentials(options.getAwsAccessKey().get(), options.getAwsSecretKey().get()));
        AWSSecurityTokenServiceClientBuilder stsBuilder = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(provider);
        AWSSecurityTokenService sts = stsBuilder.build();

        AWSCredentialsProvider credentialsProvider = new STSAssumeRoleSessionCredentialsProvider.Builder(options.getAwsRoleArn().get(), options.getAwsRoleSession().get())
                .withExternalId(options.getAwsExternalId().get())
                .withStsClient(sts)
                .build();
        options.setAwsCredentialsProvider(credentialsProvider);

        runBigQueryTornadoes(options);
    }

当我运行上面的代码时，我得到以下异常

我使用以下

mvn

命令运行

mvn compile exec:java -Dexec.mainClass=org.apache.beam.examples.cookbook.BigQueryTornadoesS3STS "-Dexec.args=..." -P direct-runner

我在网上看到了类似的帖子。但我面临的问题是没有将其打包为jar。

这篇文章帮助我使代码正常工作。通过下面的代码，我能够承担跨帐户IAM角色，并写入另一个AWS帐户拥有的S3存储桶

        Options options = PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);

        AWSCredentialsProvider provider = new AWSStaticCredentialsProvider(new BasicAWSCredentials(options.getAwsAccessKey().get(), options.getAwsSecretKey().get()));
        AWSSecurityTokenServiceClientBuilder stsBuilder = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(provider);
        AWSSecurityTokenService sts = stsBuilder.build();

        STSAssumeRoleSessionCredentialsProvider credentials = new STSAssumeRoleSessionCredentialsProvider.Builder(options.getAwsRoleArn().get(), options.getAwsRoleSession().get())
                .withExternalId(options.getAwsExternalId().get())
                .withStsClient(sts)
                .build();

        options.setAwsCredentialsProvider(
                new AWSStaticCredentialsProvider(
                        credentials.getCredentials()));

        runBigQueryTornadoes(options);
    }

注意：代码基于

bigQueryTornados

中的示例https://github.com/apache/beam
