Java连接redis集群报错，connection refused 和Could not get a resource from the pool

在使用Jedis进行redis集群操作的时候，出现报错connection refused 和Could not get a resource from the pool代码如下：

@Test
public void testRedis(){
final String redisURL = "192.168.3.3";
final String auth = "pass";
final int port7001 = 5001;
final int port7002 = 5002;
final int port7003 = 5003;
final int port7004 = 5004;
final int port7005 = 5005;
final int port7006 = 5006;

final int MAX_IDLE = 200;
final int MAX_TOTAL = 1024;
final int CONN_TIME_OUT = 1000;//链接server超时
final int SO_TIME_OUT = 1000;//等待response超时
final int MAX_ATTEMPTS = 1;//尝试重新链接次数

GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
poolConfig.setMaxTotal(MAX_TOTAL);
poolConfig.setMaxIdle(MAX_IDLE);

HostAndPort hostAndPort1 = new HostAndPort(redisURL,port7001);
HostAndPort hostAndPort2 = new HostAndPort(redisURL,port7002);
HostAndPort hostAndPort3 = new HostAndPort(redisURL,port7003);
HostAndPort hostAndPort4 = new HostAndPort(redisURL,port7004);
HostAndPort hostAndPort5 = new HostAndPort(redisURL,port7005);
HostAndPort hostAndPort6 = new HostAndPort(redisURL,port7006);

Set<HostAndPort> hostAndPortSet = new HashSet<>(6);
hostAndPortSet.add(hostAndPort1);
hostAndPortSet.add(hostAndPort2);
hostAndPortSet.add(hostAndPort3);
hostAndPortSet.add(hostAndPort4);
hostAndPortSet.add(hostAndPort5);
hostAndPortSet.add(hostAndPort6);

// public JedisCluster(Set<HostAndPort> jedisClusterNode, int connectionTimeout,
// int soTimeout, int maxAttempts, String password, GenericObjectPoolConfig poolConfig)
JedisCluster jedisCluster = new JedisCluster(hostAndPortSet,CONN_TIME_OUT,SO_TIME_OUT,MAX_ATTEMPTS,auth,poolConfig);

jedisCluster.set("a", "1o");
System.out.println(jedisCluster.get("a"));

//
// public JedisPool(GenericObjectPoolConfig poolConfig, String host, int port, int timeout, String password) {
// this(poolConfig, host, port, timeout, password, 0, (String)null);
// }

}

经过查找资料，最终猜测问题出在redis-cluster/redis**/nodes_**.conf，所以对此文件进行了修改

注：修改时请先关闭集群
修改之前的文件内容如下：

ＰＳ：此博主最终的解决方法是重做集群，不过我并没有重做集群，只是修改了一下所有节点的nodes**_conf文件并重启，也可以解决问题，目前来看并没有什么不妥，如果有问题再回来修改 ×——×
