--------------------------------------
Summary: Arg checking & better doc for SSHOperator and SFTPOperator
Key: AIRFLOW-2948
URL: https://issues.apache.org/jira/browse/AIRFLOW-2948
Project: Apache Airflow
Issue Type: Improvement
Components: operators
Reporter: Xiaodong DENG
Assignee: Xiaodong DENG
There may be different combinations of arguments, and some processings are
being done 'silently', while users may not be fully aware of them.
For example
- User only needs to provide either `ssh_hook` or `ssh_conn_id`, while this is
not clear in doc
- if both provided, `ssh_conn_id` will be ignored.
- if `remote_host` is provided, it will replace the `remote_host` which
wasndefined in `ssh_hook` or predefined in the connection of `ssh_conn_id`
These should be documented clearly to ensure it's transparent to the users.
log.info() should also be used to remind users and provide clear logs.
