scala - 具有Scala和elastic4s的IndexMissingException

Question

您好stackoverflowers!

我尝试将库Elastic4s与Scala结合使用，但是当我运行以下代码时(以获取索引广告中的广告列表):

trait elastic4s {
  def get: Future[SearchResponse] = {
    val client = ElasticClient.local
    client execute { search in "ads"->"ad" }
  }
}

我有这个异常(exception):

An error has occured: org.elasticsearch.indices.IndexMissingException: [ads] missing

Pastebin与 full output here.

这是我的配置:

-- Java
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

-- ElasticSearch
version 1.0.1

-- Elastic4s
version 2.10-1.0.1 

Elastic Search已在localhost:9200上启动并运行，并且该索引广告存在。此CURL请求:

curl -XGET 'http://localhost:9200/ads/ad/_search'

            "_source": {
                "json": "json"
            }
        }
    ]
    }
}

我不明白...如果有人可以给我一个音轨:)

本地节点不会与在该进程外运行的其他Elasticsearch实例通信。本地节点是JVM本地的。

代码注释说:

"Is the node a local node. A local node is a node that uses a local (JVM level) discovery transport. Other (local) nodes started within the same JVM (actually, class-loader) will be discovered and communicated with. Nodes outside of the JVM will not be discovered."

您需要使用远程客户端连接到外部实例，即使它们在本地运行。我想这似乎违反直觉，但远程确实意味着基于IPC或Socket。
