Java 带有数据流的ApacheBeamGoSDK

我一直在使用Go Beam SDK（v2.13.0），无法获得GCP数据流方面的工作。它进入崩溃循环，试图启动

org.apache.beam.runners.dataflow.worker.DataflowRunnerHarness

。当使用Direct runner在本地运行时，该示例正在正确执行

该示例完全没有对上面给出的原始示例进行修改

堆栈跟踪是：

我再次尝试了getting started中提供的docker，以及使用v2.13.0构建的docker

示例文件的go.mod为：

module example.org/wordcount

go 1.12

require (
    cloud.google.com/go v0.41.0 // indirect
    github.com/apache/beam v2.13.0+incompatible
    github.com/pkg/errors v0.8.1 // indirect
    golang.org/x/net v0.0.0-20190628185345-da137c7871d7 // indirect
    google.golang.org/grpc v1.22.0 // indirect
)

是什么导致了这种情况？

数据流没有正式支持Apache Beam Go SDK。不过，一些用户已经能够使用它了。我怀疑这个版本可能有问题。您可以尝试不同的版本

---

您可以与其他用户讨论哪些版本适用于他们（尽管不受支持）。

我也有同样的问题。将Beam版本增加到2.19对我来说很有用

---

看起来他们以向后不兼容的方式重新排列了一些Beam Fn API protos，因此您需要确保使用的是最新版本的Beam Go SDK。

堆栈转储表明错误来自尝试解析管道图Protobuffer，但UTF-8编码无效。您是否对wordcount示例进行了任何修改（如添加步骤名称）？您还可以分享您是如何启动作业的吗？@Cubez更新为包含使用的命令，并指定源代码根本没有从示例中修改。到目前为止，我已经尝试了多个版本。我很想知道什么版本的组合是有效的——我可能可以复制一个工作版本，但我可能猜不出go release、protoc和Beam SDK的神奇组合。因为这不是官方支持的，另一个Beam用户可能可以帮助您选择适用于他们的版本，并可能共享依赖项文件。您可以在此处找到beam的用户邮件列表。
