当我尝试使用 play2-elastic 插件从非本地机器连接到安装在 EC2 上的 ElasticSearch (elasticsearch-0.90.3) 时，它会引发以下异常（该插件在本地连接时工作正常）
error] application - ElasticSearch : No ElasticSearch node is available. Please check that your configuration is correct, that you ES server is up and reachable from the network. Index has not been created and prepared.

我使用了不同的方法来测试 elasticsearch 服务器是否启动并运行，示例：
curl -XGET '184.72.55.204:9300/_analyze?analyzer=standard' -d 'this is a test'
curl: (52) Empty reply from server
telnet 184.72.55.204 9300
Trying 184.72.55.204...
Connected to ec2-184-72-55-204.us-west-1.compute.amazonaws.com.
Escape character is '^]'.
在一些谷歌群组中，我也看到其他人有类似的问题，他们似乎能够通过关闭嗅探来解决问题，所以我的 application.conf 中有这个
elasticsearch.client="184.72.55.204:9300"
elasticsearch.sniff=false # I ADDED THIS BUT DID NOT HELP
elasticsearch.index.name="phonotags"
elasticsearch.index.settings="{ analysis: { analyzer: { my_analyzer: { type: \"custom\", tokenizer: \"standard\" } } } }"
elasticsearch.index.clazzs="indexing.*"
elasticsearch.index.show_request=true
我的 build.scala 文件包含这些：
"com.clever-age" % "play2-elasticsearch" % "0.7-SNAPSHOT"
resolvers += Resolver.url("play-plugin-releases", new URL("http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns),
resolvers += Resolver.url("play-plugin-snapshots", new URL("http://repo.scala-sbt.org/scalasbt/sbt-plugin-snapshots/"))(Resolver.ivyStylePatterns)
我感谢您的帮助。谢谢
