python - pyspider使用redis分布式

在部署pyspider分布式时,尝试连接redis集群
配置项为： "message_queue":"redis://127.0.0.1:6380/db"
在启动时：报如下错误
[E 170221 09:40:39 tornado_fetcher:529] MOVED 12068 127.0.0.1:6380

经查找，得到：因为redis由单节点变为集群，而python的redis连接包暂时还不支持redis集群连接方式，需要更换连接包（redis-py-cluster）。

在安装完redis-py-cluster之后，依旧报上面的错误。
