Q:

org.redisson.client.RedisNodeNotFoundException: Node: NodeSource hasn't been discovered yet

I am new to Redisson and I was trying to integrate the redisson + spring boot for distributed locks with the help of Redis cache.
I am getting below error:
org.redisson.client.RedisNodeNotFoundException: Node: NodeSource [slot=14577, addr=redis://10.150.77.93:6381, redisClient=null, redirect=MOVED, entry=null] hasn't been discovered yet.

The Redis Cache is autoconfigured by Spring boot and I have configured the RedissonClient for master slave cluster.
@Configuration
public class RedissonConfiguration
{
   @Bean
   RedissonClient redissonClient(Config config)
   {
     return Redisson.create(config);
   }

  @Bean
  Config config()
  {
    Config config =  new Config();
    config.useMasterSlaveServers().setMasterAddress("redis://10.150.77.91:6381")
            .addSlaveAddress("redis://10.150.77.93:6382");
    return config;
}
}

 @Component
 public class TriggerHandler
 {
private static final Logger LOGGER = LoggerFactory.getLogger(TriggerHandler.class);

@Autowired
RedissonClient redissonClient;

@Async
public void triggerEvent(AsyncEventTriggerRequest eventTriggerRequest)
{

    String lockName = eventTriggerRequest.getTenantId().concat("lock");

    RLock lock = redissonClient.getLock(lockName);

    try
    {
        if(lock.tryLock(2,5, TimeUnit.SECONDS))
        {
            LOGGER.info("Lock has been Achieved for: {}", lockName);
        }
    }
    catch (InterruptedException e)
    {
        lock.forceUnlock();
        e.printStackTrace();
    }

    lock.unlock();

}
}

Why is it failing ? Does not Redisson auto confiures redis client for Redis ?

A:

This error means that Redis node 10.150.77.93 is not discovered yet, since Redis cluster info doesn't contain any information about it.
