> handle socket exception with SFTPOperator
> -----------------------------------------
>
> Key: AIRFLOW-3528
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3528
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: 1.10.1
> Reporter: Elad
> Assignee: Elad
> Priority: Major
>
> Currently SFTPOperator executes:
>
> {code:java}
> sftp_client = ssh_client.open_sftp()
> {code}
> without handling socket errors.
> If error occurs with the connection the operator show the following message:
> {code:java}
> Subtask: airflow.exceptions.AirflowException: Error while transferring None,
> error: 'NoneType' object has no attribute 'open_sftp'{code}
> This error is misleading because it suggests that there is a problem with the
> file transfer yet the problem in fact can be with the connection.
>
> The issue reported by lot on Slack.
