Question

我试图在Windows上启动两个ElasticSearch节点。如果我使用多播，则节点会正常启动。但是，我在尝试使用单播时遇到异常。

我的设置是：

cluster.name: mycluster
name.name: NODE1
node.master: true
node.data: true
index.number_of_shards: 5
index.number_of_replicas: 1
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["node2:9200"]

和

cluster.name: mycluster
name.name: NODE2
node.master: false # tried true as well
node.data: true
index.number_of_shards: 5
index.number_of_replicas: 1
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["node1:9200"]

我可以在node1上成功启动ES但是当我尝试在node2上启动ES时，我在node1中得到以下异常：

[2013-10-11 15:04:02,307][WARN ][http.netty               ] [NODE1] Caught exception while handling client http traffic, closing connection [id: 0x4061b93e, /10.241.2.96:58768 :> /10.241.1.70:9200]

  at org.elasticsearch.common.netty.channel.DefaultChannelPipeline.sendUpstream(DefaultChannelPipeline.java:559)
...

我的环境：

Elastic Search Version on both node1 and node2: 0.90.3
Java version: 
    java version "1.7.0"
    Java(TM) SE Runtime Environment (build 1.7.0-b147)
    Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

有什么想法在这里发生了什么？

谢谢，埃里克

Answer 1

9200是数据端口

单播发现从控制端口9300发生......

Answer 2

我犯的错误是将其他节点的端口设置为9200.我不是这方面的专家（正如您可以通过我的问题所说）但我认为9200是客户端用来与之交互的端口搜索引擎;但是其他ES实例默认使用不同的端口（可能是9300）。通过改变：

discovery.zen.ping.unicast.hosts: ["node1:9200"]

为：

discovery.zen.ping.unicast.hosts: ["node1"]

事情对我来说很好。
