too many cluster redirections?; nested exception is redis.clients.jedis.exce

使用redis的jediscluster客户端进行测试出现以下异常

Exception in thread "main" redis.clients.jedis.exceptions.JedisClusterMaxRedirectionsException: Too many Cluster redirections?

错误原因：

创建redis集群的时候使用的命令是：./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006

但是由于java客户端在集群之外所以是这样写的：

Set<HostAndPort> nodes=new HashSet<HostAndPort>();
       nodes.add(new HostAndPort("192.168.0.104", 7001));
       nodes.add(new HostAndPort("192.168.0.104", 7002));
       nodes.add(new HostAndPort("192.168.0.104", 7003));
       nodes.add(new HostAndPort("192.168.0.104", 7004));
       nodes.add(new HostAndPort("192.168.0.104", 7005));
       nodes.add(new HostAndPort("192.168.0.104", 7006));
       JedisCluster jc=new JedisCluster(nodes);
       jc.set("key1", "hello word");

host地址不匹配，导致Too many Cluster redirections

所以重新构建集群使用：./redis-trib.rb create --replicas 1 192.168.0.104:7001 192.168.0.104:7002 192.168.0.104:7003 192.168.0.104:7004 192.168.0.104:7005 192.168.0.104:7006
