Airflow 1.9 - SSHOperator似乎不起作用？

Question

升级到v1.9，我很难让SSHOperator工作。它与w1.8.2一起工作。

代码

dag = DAG('transfer_ftp_s3', default_args=default_args,schedule_interval=None)

task = SSHOperator(
       ssh_conn_id='ssh_node',
       task_id="check_ftp_for_new_files",
       command="echo 'hello world'",
       do_xcom_push=True,
       dag=dag,)

错误

作为AIRFLOW-2122检查你的连接设置，使用字符串而不是bool确保额外的值
