我正在使用Couchbase-Java-Client-2.5.0和couchbase-server-community_4.5.1-ubuntu14.04_amd64.deb。
我在群集中有两个节点，两个节点都在AWS中。
尝试运行代码时，控制台中的连接超时和信号断开连接。如果我使用单个节点，则运行相同的代码。
使用的代码：
CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder().connectTimeout(50000).socketConnectTimeout(50000).kvTimeout(60000).searchTimeout(10000).build();
Cluster cluster = CouchbaseCluster.create(env, "ec2-13-56-229-101.us-west-1.compute.amazonaws.com", "ec2-54-183-207-37.us-west-1.compute.amazonaws.com");
Bucket bucket = cluster.openBucket("StellarA","*****");
JsonObject person = JsonObject.create();
person.put("firstname", "Sweta");
person.put("lastname", "Kedia");
JsonDocument document = JsonDocument.create("sweta", person);
bucket.upsert(document);
System.out.println(bucket.get("sweta").content());
控制台输出：

在AWS中，当客户端无法解析主机名或打开与群集配置标识的已解析IP的连接时，会出现此类问题。您可以仔细检查configured the cluster per the documentation on AWS deployments或run the SDK-Doctor的方式，以便诊断常见的错误配置。
