Redis Cluster: Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

Hi,

I have created redis cluster with default scripts from latest stable redis 3.0.0 release and cluster is created successfully. $redis-3.0.0/utils/create-cluster# ./create-cluster start Starting 30001(M) Starting 30002(M) Starting 30003(M) Starting 30004(S) Starting 30005(S) Starting 30006(S) $redis-3.0.0/utils/create-cluster# ./create-cluster create

And I’m implemented a small java main method class to test the redis cluster using Jedis 7.0 API, Snippet:

public class RedisCTest {

public static void main(String[] args) {

    Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
    //Jedis Cluster will attempt to discover cluster nodes automatically
    jedisClusterNodes.add(new HostAndPort("host", 30001));
    jedisClusterNodes.add(new HostAndPort("host", 30002));
    jedisClusterNodes.add(new HostAndPort("host", 30003));
    JedisCluster jc = new JedisCluster(jedisClusterNodes);
    System.out.println("Cluster Size...." + jc.getClusterNodes().size());
    jc.set("foo1", "bar1");
    jc.set("foo2", "bar2");
    jc.set("foo3", "bar3");
    jc.set("foo4", "bar4");

}

} First time it is working fine and keys are stored into redis , when I run this program multiple time’s, I’m getting below exception:

Console Output:

Thanks!

@marcosnils : Thanks for your support, we greatly appreciate your help!

we have successfully done remote connectivity from client to Redis Cluster. by replacing Bind IP(127.0.0.1) in redis.conf file with machine IP.
