redis4.0 集群，jedis客户端连接踩坑

使用jedis 2.9.0连接，异常信息：

redis.clients.jedis.exceptions.JedisDataException: ERR Client sent AUTH, but no password is set。

说我没有设置密码，当时我就震惊了。我明明设置了密码呀。我用redis-cli连接的时候 还让我输入密码了呢～

检查了好久才想起来，redis-cli默认连接6379，我只给6379设置密码了，实际上要给每个节点都设置密码：

config set masterauth abc
config set requirepass abc  

spring配置，jedis连接集群，竟然没有RedisCluster一个构造函数的参数只由 Set<HostAndPort>和password组成，害得我还要配置这么多参数。
