> Key: AIRFLOW-4236
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4236
> Project: Apache Airflow
> Issue Type: Bug
> Components: gcp, operators
> Affects Versions: 1.10.3
> Reporter: jack
> Assignee: Ryan Yuan
> Priority: Major
> Labels: easy-fix
>
> I got HTTP 500 error when using the MySqlToGoogleCloudStorageOperator this
> error caused the operator to fail and a 3 hours job were gone to waste.
> This error should not cause the operator to fail immediately. It should first
> try to retry the upload as suggested :
> [https://stackoverflow.com/questions/23945784/how-to-manage-google-api-errors-in-python]
> There should be at least 2 attempts to retry before giving up.
