Question

我正在尝试使用GCP上的DataflowRunner运行我的Java数据流。

Dataflow可以正常使用DirectRunner但是当更改为DataflowRunner并运行它时，控制台开始暂存文件，我突然多次收到以下错误：

但是暂存继续（因为控制台仍然输出一些暂存信息）并且在某些时候错误再次弹出（可能是第5次）然后是以下内容：

mars 19, 2018 8:48:13 PM org.apache.beam.runners.dataflow.util.PackageUtil stageClasspathElements
INFOS: Still staging 127 files

正如控制台所说，它仍处于升级状态，并且无法理解这是暂存问题还是与我的代码执行相关...

关于它的任何想法以及如何解决这个问题？

**编辑** 还有一个我之前没有注意到的错误：

Answer 1

这实际上是一个网络问题。解决方法解决方案是通过Compute Engine实例部署管道。这将确保您获得良好的网络带宽。
