Redis3 集群设置密码 JedisCluster 连接显示没有权限，求大神指点

Question

使用版本：
Redis3
Jedis2.8

出现问题：Redis3集群设置了密码，在程序中Jedis2.8 通过JedisCluster 操作redis
系统报错

```redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.
at redis.clients.jedis.Protocol.processError(Protocol.java:117) ~[jedis-2.8.0.jar:na]
at redis.clients.jedis.Protocol.process(Protocol.java:151) ~[jedis-2.8.0.jar:na]

**经查证资料发现**
JedisCluster 中  jedisCluster.auth(password)；方法并没有实现其具体内容。
**根据网上搜索资料**

在底层插入密码设定片段如下：

private void initializeSlotsCache(Set startNodes, GenericObjectPoolConfig poolConfig) {
for (HostAndPort hostAndPort : startNodes) {
Jedis jedis = new Jedis(hostAndPort.getHost(), hostAndPort.getPort());
jedis.auth("此处已输入正确密码");
try {
cache.discoverClusterNodesAndSlots(jedis);
break;
} catch (JedisConnectionException e) {
// try next nodes

可是问题依然存在，redis集群上个节点已经设定统一的密码，
   jedis.auth("将此处输入错误密码");
     会出现以下报错

     输入正确密码依然报NOAUTH Authentication required.


     求大神指点
