Elasticsearch集群'master_not_discovered_exception' [英] Elasticsearch cluster 'master_not_discovered_exception'

问题描述

我已经安装了Elasticsearch 2.2.3并在2个节点的集群中进行了配置

i have installed elasticsearch 2.2.3 and configured in cluster of 2 nodes

节点1（elasticsearch.yml）

Node 1 (elasticsearch.yml)

cluster.name: my-cluster
node.name: node1
bootstrap.mlockall: true
discovery.zen.ping.unicast.hosts: ["ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com", "ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com"]
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.multicast.enabled: false
indices.fielddata.cache.size: "30%"
indices.cache.filter.size: "30%"
node.master: true
node.data: true
http.cors.enabled: true
script.inline: false
script.indexed: false
network.bind_host: 0.0.0.0

节点2（elasticsearch .yml）

Node 2 (elasticsearch.yml)

cluster.name: my-cluster
node.name: node2
bootstrap.mlockall: true
discovery.zen.ping.unicast.hosts: ["ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com", "ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com"]
discovery.zen.minimum_master_nodes: 1
discovery.zen.ping.multicast.enabled: false
indices.fielddata.cache.size: "30%"
indices.cache.filter.size: "30%"
node.master: false
node.data: true
http.cors.enabled: true
script.inline: false
script.indexed: false
network.bind_host: 0.0.0.0

如果我得到 curl -XGET'http：// localhost：9200 / _cluster / state？pretty'我有：

{
  "error" : {
    "root_cause" : [ {
      "type" : "master_not_discovered_exception",
      "reason" : null
    } ],
    "type" : "master_not_discovered_exception",
    "reason" : null
  },
  "status" : 503
}

到节点1的日志中有：

[2016-06-22 13:33:56,167][INFO ][cluster.service          ] [node1] new_master {node1}{Vwj4gI3STr6saeTxKkSqEw}{127.0.0.1}{127.0.0.1:9300}{master=true}, reason: zen-disco-join(elected_as_master, [0] joins received)
[2016-06-22 13:33:56,210][INFO ][http                     ] [node1] publish_address {127.0.0.1:9200}, bound_addresses {[::]:9200}
[2016-06-22 13:33:56,210][INFO ][node                     ] [node1] started
[2016-06-22 13:33:56,221][INFO ][gateway                  ] [-node1] recovered [0] indices into cluster_state

而不是节点2的日志中：

Into log of node 2 instead:

[2016-06-22 13:34:38,419][INFO ][discovery.zen            ] [node2] failed to send join request to master [{node1}{Vwj4gI3STr6saeTxKkSqEw}{127.0.0.1}{127.0.0.1:9300}{master=true}], reason [RemoteTransportException[[node2][127.0.0.1:9300][internal:discovery/zen/join]]; nested: IllegalStateException[Node [{node2}{_YUbBNx9RUuw854PKFe1CA}{127.0.0.1}{127.0.0.1:9300}{master=false}] not master for join request]; ]

哪里出错了？

推荐答案

我用以下代码行解决：

network.publish_host：ec2-xx-xx-xx-xx。 eu-west-1.compute.amazonaws.com

每个 elasticsearch.yml 配置文件必须在此行中输入您的主机名

every elasticsearch.yml config file must have this line with your hostname
