JedisConnectionFactory error: redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required

[nitinware]

Expected behavior

I am expecting the establish the connection with AWS ElasticCache Redis cluster successfully and JedisConnectionFactory object initialized successfully

Actual behavior

On application startup, I am seeing below error on throw when initializing JedisConnectionFactory:

Failed to instantiate [org.springframework.data.redis.connection.jedis.JedisConnectionFactory]: Factory method 'clusterModeJedisConnectionFactory' threw exception; nested exception is redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.\n\tat org.springframework.beans.factory.support.ConstructorResolver.instantiate(ConstructorResolver.java:658)\n\tat org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:486)\n\tat org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateUsingFactoryMethod(AbstractAutowireCapableBeanFactory.java:1352)\n\tat

Steps to reproduce:

Redis / Jedis Configuration

 @Bean
    @Conditional(RedisClusterModeCondition.class)
    public JedisConnectionFactory clusterModeJedisConnectionFactory() {
        RedisClusterConfiguration configuration = new RedisClusterConfiguration()
                .clusterNode(redisHostName, redisPort);
        configuration.setMaxRedirects(5);
        JedisClientConfiguration clientConfiguration = sslEnabled?
                JedisClientConfiguration.builder().useSsl().and().usePooling().build() :
                JedisClientConfiguration.builder().build();
        JedisConnectionFactory factory = new JedisConnectionFactory(configuration, clientConfiguration);
        factory.afterPropertiesSet();
        logger.info(String.format("Configuring Redis ClusterMode with host: %s and port: %d", redisHostName, redisPort));
        return factory;
    }

The Redis cluster have a default user with no password configured:

Jedis version:

3.6.3

Redis version:

5.0.6

Java version:

openjdk1.8.0.342_8.64.0.16_x64

NOAUTH Authentication required. error comes from Redis server. Jedis doesn't generate it on its own.

We can't learn how aws manages things at this moment. Please consult with them (or, maybe Spring). Thanks
