	cmd := fmt.Sprintf(`/cdc cli changefeed list --server "%s"`, t.TiCDCServer)
	output, err := t.exec(cmd)
	if err != nil  {
		return nil, err
	}

	var changefeedlist []Changefeed
	if err := json.Unmarshal([]byte(output), &changefeedlist); err != nil {
		return nil, errors.New("fialed to unmarshal changefeed list" + err.Error())
	}
	return changefeedlist, nil
}
