Dataflow 作业在 BigQuery 写入时失败并出现后端错误 [英] Dataflow job fails at BigQuery write with backend errors

问题描述

我有一份工作失败，有几个与最终导入 BigQuery 相关的不同错误.我已经运行了 5 次，但每次都失败，尽管错误消息有时会有所不同.当我在本地针对 SQLite 数据库运行它时，这项工作运行良好，所以我认为问题出在 Google 后端.

I have a job which is failing with several different errors related to the final import into BigQuery. I've run it 5 times and it fails each time, though the error message sometimes varies. The job worked fine when I ran it locally against an SQLite database, so I think the problem is on the Google backend.

一条错误信息:

**Workflow failed. Causes: S04:write meter_traces_combined to BigQuery/WriteToBigQuery/NativeWrite failed., BigQuery import job "dataflow_job_5111748333716803539" failed., BigQuery creation of import job for table "meter_traces_combined" in dataset "ebce" in project "oeem-ebce-platform" failed., BigQuery execution failed., Unknown error.**

推荐答案

Google Cloud Support 在这里.我检查了你的工作，我发现了两个可能与这次失败有关的内部问题.正如 Alex Amato 在他的评论中所建议的那样，我会尝试使用

Google Cloud Support here. I have inspected your job and I found two internal issues which might be related to this failure. As suggested by Alex Amato in his comment, I would try to use

--experiments=use_beam_bq_sink

否则，我建议您直接在 GCP 上开工单，因为这可能需要进一步调查.

Otherwise, I would recommend you to open a ticket on GCP directly because this might take further investigation.

希望能帮到你.
