我正在如下使用MySqlToGoogleCloudStorageOperator。
Dag任务详细信息
def gen_export_table_task(table_config):
export_task = MySqlToGoogleCloudStorageOperator(task_id='export_dag_run_to_gcs',
dag=dag,
sql='SELECT * FROM dag_run LIMIT 10',
bucket='gs://aca-composer-bq-test-vishesh',
filename="cloudsql_to_bigquery_file.json",
google_cloud_storage_conn_id='google_cloud_storage_default',
mysql_conn_id='airflow_db')
return export_task
请在下面查看我在执行DAG时得到的错误详细信息:
