title: Airflow: Log file isn't local, Unsupported remote log location
body: <p>I am not able see the logs attached to the tasks from the Airflow UI:

  <p>Log related settings in airflow.cfg file are:</p>
  
  <ul>
  <li><code>remote_base_log_folder =</code></li>
  <li><code>base_log_folder = /home/my_projects/ksaprice_project/airflow/logs</code></li>
  <li><code>worker_log_server_port = 8793</code> </li>
  <li><code>child_process_log_directory =
  /home/my_projects/ksaprice_project/airflow/logs/scheduler</code></li>
  </ul>
  
  <p>Although I am setting remote_base_log_folter it is trying to fetch the log from <code>http://:8793/log/tutorial/print_date/2017-08-02T00:00:00</code> - I don't understand this behavior. According to the settings the workers should store the logs at <code>/home/my_projects/ksaprice_project/airflow/logs</code> and they should be fetched from the same location instead of remote.  </p>
