我的TransportClient看起来像这样：
public synchronized Client getClient(String clusterName, List<String> hosts, Integer port) {
// Build the settings for our client.
Settings settings = Settings.settingsBuilder()
.put("transport.ping_schedule", "5s")
.put("cluster.name", clusterName)
.put("action.bulk.compress", false)
.put("shield.transport.ssl", true)
.put("request.headers.X-Found-Cluster", clusterName)
.put("shield.user", "USERNAME:PASSWORD")
.build();
TransportClient client = clients.get(clusterName);
if (client == null) {
client = TransportClient.builder().addPlugin(ShieldPlugin.class).settings(settings).build();
clients.put(clusterName, client);
for(String host : hosts) {
try {
for (InetAddress address : InetAddress.getAllByName(host)) {
if (address instanceof Inet4Address) {
client.addTransportAddress(new InetSocketTransportAddress(address, port));
}
}
} catch (UnknownHostException e) {
throw new ElasticSearchException(e);
}
}
try {
logger.info("Getting cluster health... ");
ActionFuture<ClusterHealthResponse> healthFuture = client.admin().cluster().health(Requests.clusterHealthRequest());
ClusterHealthResponse healthResponse = healthFuture.get(5, TimeUnit.SECONDS);
logger.info("Got cluster health response: [{}]", healthResponse.getStatus());
} catch(Throwable t) {
logger.error("Unable to get cluster health response: [{}]", t.getMessage());
}
}
return client;
}
我的传输客户端如果失败并显示以下堆栈跟踪：
org.elasticsearch.client.transport:383 [Abraham Cornelius] failed to get node info for {#transport#-1}{000.000.000.000}{XXX.us-east-1.aws.found.io/000.000.000.000:9343}, disconnecting...

当我运行IDE，IntelliJ时，一切运行正常。但是当我直接运行胖罐时，kaboom。
答案 0 :(得分：5)
here描述了这个问题的解释。简而言之，ElasticSearch及其lucene依赖项在META-INF / services中具有冲突的文件，当它们组合在一个jar中时，它们会被相互覆盖。
如果你遇到这个问题，你可能会建立一个罐子。如果您正在使用maven，您可以使用shade插件来解决这个问题，以合并这些文件并防止它们被覆盖：
