在 EC2 服务器上安装 ElasticSearch 时 play2-elastic 不起作用

Question

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.
org.elasticsearch.client.transport.NoNodeAvailableException: No node available

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)

感谢您的帮助。 谢谢

您的节点似乎不可用

curl -XPUT '184.72.55.204:9200/twitter/tweet/1' -d '{ "user": "kimchy", "post_date" : "2011-08-18T16:20:00", "message" : "trying out Elastic Search" }'

你能检查一下吗？
