BigQuery with Airflow - 缺少projectId

Question

尝试下面的例子：

https://cloud.google.com/blog/big-data/2017/07/how-to-aggregate-data-for-bigquery-using-apache-airflow

运行命令之一时：

airflow test bigquery_github_trends_v1 bq_check_githubarchive_day 2017-06-02

收到错误：TypeError：缺少所需参数“projectId”

如果你检查bigquery_hook的代码，你会发现它正在检查project_id，https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/hooks/bigquery_hook.py#L54

默认连接是 bigquery_default ，除非您覆盖它，转到 Airflow UI，转到管理 --> 连接 --> bigquery_default （或您创建的任何内容） --> 在那里添加项目 ID
