如何通过 Apache Beam 将文件上传到 Azure blob 存储？

Question

我想通过 Apache Beam 将文件上传到 Azure blob。但是，我做不到。为什么？

我设置了正确的环境变量。

az 命令正常：

$ az storage blob upload \
-c AZURE_STORAGE_CONTAINER_NAME \
-f example.json -n example.json \
--account-name $AZURE_STORAGE_ACCOUNT \
--account-key $AZURE_STORAGE_KEY                                                                        
Finished[#############################################################]  100.0000%
{
  "etag": "\"0x8D9B92C4C0BE870\"",
  "lastModified": "2021-12-07T02:50:15+00:00"
}

但是，下面的命令运行：

$ mvn compile exec:java -Dexec.mainClass=jp.example.Indexer \
-Dexec.args="--runner=DirectRunner \
--destination=azfs://$AZURE_STORAGE_ACCOUNT/$AZURE_STORAGE_CONTAINER_NAME/example.json \
--source=example.json \
--azureConnectionString=$AZURE_CONNECTION_STRING \
--sasToken=$AZURE_STORAGE_SAS_TOKEN \
--accessKey=$AZURE_STORAGE_KEY \
--accountName=$AZURE_STORAGE_ACCOUNT

然后，出现以下错误：

Indexer.java来了。

package jp. example;

import java.util.logging.Logger;
import org.apache.beam.sdk.Pipeline;
import org.apache.beam.sdk.io.TextIO;
import org.apache.beam.sdk.options.PipelineOptionsFactory;
import org.apache.beam.sdk.values.PCollection;


public class Indexer {

    private static final Logger LOG = Logger.getLogger(Indexer.class.getName());

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

        PCollection<String> lines = p.apply(TextIO.read().from(options.getSource()));

        lines.apply(TextIO.write().to(options.getDestination()));

        p.run();
    }
}

ToAzurePipelineOptions.java 在这里。

package jp.example;

import org.apache.beam.runners.dataflow.options.DataflowPipelineOptions;
import org.apache.beam.sdk.io.azure.options.BlobstoreOptions;
import org.apache.beam.sdk.options.Default;
import org.apache.beam.sdk.options.Description;

public interface ToAzurePipelineOptions extends DataflowPipelineOptions, BlobstoreOptions{

    @Description("Root path of data files")
    @Default.String("file://hoge")
    String getSource();

    void setSource(String value);

    @Description("Address of Azure Storage")
    @Default.String("azfs://hoge")
    String getDestination();

    void setDestination(String value);
}

beam-sdks-java-io-azure和beam-sdks-java-core的版本是2.31.0。

Answer 1

我猜这可能是因为 TokenCredentialSerializer 仅在 Beam 2.33.0 中是 implemented。您能否将 Beam 依赖项至少升级到 Beam 2.33.0，看看它是否能解决问题？
