我尝试通过SSL连接到我的弹性搜索服务器并尝试了很多不同的东西，但无法解决问题。 目前我正在使用elasticsearch 2.3.3和jdk1.7.0_79。
编辑：首先，我尝试使用以下代码在Netbeans中使用Elastic JAVA Api进行连接：
Settings settings = Settings.settingsBuilder()
.put("cluster.name", CLUSTER_NAME)
.put("shield.user", "USER:PASSWORD")
.put("transport.ssl.keystore.path", "/usr/share/elasticsearch/bin/shield/KEYSTORE.jks")
.put("transport.ssl.keystore.keystore_password", KEYSTORE_PASSWORD)
.put("shield.transport.ssl", true).build();
Client client = TransportClient.builder().settings(settings).build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(HOST), 9300));
上一个示例适用于我的弹性localhost服务器，但是当我尝试将其迁移到使用SSL的Web服务器时，它每隔5秒输出一次：
976 [main] DEBUG org.elasticsearch.client.transport - [Miguel Espinosa] adding address [{#transport#-1}{IP_ADDRESS}{HOST/IP_ADDRESS:9300}]
1059 [main] DEBUG org.elasticsearch.transport.netty - [Miguel Espinosa] connected to node [{#transport#-1}{IP_ADDRESS}{HOST/IP_ADDRESS:9300}]
1200 [elasticsearch[Miguel Espinosa][generic][T#1]] DEBUG org.elasticsearch.transport.netty - [Miguel Espinosa] disconnecting from [{#transport#-1}{IP_ADDRESS}{HOST/IP_ADDRESS:9300}], channel closed event
1238 [main] INFO org.elasticsearch.client.transport - [Miguel Espinosa] failed to get node info for {#transport#-1}{IP_ADDRESS}{HOST/IP_ADDRESS:9300}, disconnecting...
NodeDisconnectedException[[][HOST/IP_ADDRESS:9300][cluster:monitor/nodes/liveness] disconnected]
之后，现在我尝试使用found-shield尝试连接弹性，但是当我运行应该工作的示例时，它会输出以下内容：

我是弹性搜索的新手，所以如果有什么不合适请问我，我会尽快给你提供。 我还检查了其他类似问题，例如SSL Elasticsearch
谢谢，伊曼纽尔

如文档中所述，您应该同步JDK版本：
在Elasticsearch的少数几个位置，使用了Java的本机序列化 （IP地址，例外等）。不幸的是，Oracle有 众所周知，改变次要版本之间的序列化格式， 导致奇怪的错误。这很少发生，但最好 练习使客户端和服务器之间的JVM版本保持一致。
