How to get Address of elasticache nodes from Java API?

Question

I am making a describeCacheClusters request as follows and get a valid response but the getCacheClusters() method returns null even though that cluster has available nodes. Is there another request I should be using or a missing parameter?

DescribeCacheClustersResult result = awsClient
        .describeCacheClusters(new DescribeCacheClustersRequest()
        .withCacheClusterId(ELASTICACHE_CLUSTER_ID));

You can generate hostname as it always has the format CLUSTER_NAME.f1xaiv.0001.use1.cache.amazonaws.com where 0001 is the number of the node. — Usman Ismail, Aug 02 '12 at 15:38

You are missing a parameter indeed due to a somewhat confusing API design resp. documentation issue with Amazon ElastiCache:

You need to add setShowCacheNodeInfo() to your DescribeCacheClustersRequest and call getCacheNodes() for each CacheCluster retrieved via getCacheClusters() from the DescribeCacheClustersResult - see my answer to the semantic duplicate Finding AWS ElastiCache endpoints with Java for details and code samples.
