Question

作为Elasticsearch的首发，我只是在两周前使用它而且我刚做了一件傻事。

我的Elasticsearch有一个集群有两个节点，一个是主数据节点（版本1.4.2），一个是非数据节点（版本1.1.1）。使用时有冲突版本，我决定关闭并删除然后，安装另一个数据节点（版本1.4.2）看看我的图像，以便于想象。 node3然后命名为node2 enter image description here

然后，我检查弹性状态

{ 
    "cluster_name":"elasticsearch",
    "status":"yellow",
    "timed_out":false,
    "number_of_nodes":2,
    "number_of_data_nodes":2,
    "active_primary_shards":725,
    "active_shards":1175,
    "relocating_shards":0,
    "initializing_shards":0,
    "unassigned_shards":273
}

检查群集状态

curl -XGET http://localhost:9200/_cat/shards

我已阅读相关问题并试图遵循它但没有运气。我也在答案中评论我得到的错误。

ElasticSearch: Unassigned Shards, how to fix?

https://t37.net/how-to-fix-your-elasticsearch-cluster-stuck-in-initializing-shards-mode.html

elasticsearch - what to do with unassigned shards

http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-reroute.html#cluster-reroute

curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
    "commands" : [ {
          "allocate" : {
              "index" : "logstash-2015.03.25", 
              "shard" : 4, 
              "node" : "node2", 
              "allow_primary" : true
          }
        }
    ]
}'

我得到了

"routing_nodes":{"unassigned":[{"state":"UNASSIGNED","primary":false,"node":null,
"relocating_node":null,"shard":0,"index":"logstash-2015.03.25"}

我按照https://stackoverflow.com/a/23781013/1920536

中的回答

curl -XPUT 'localhost:9200/_cluster/settings' -d '{
"transient" : {
    "cluster.routing.allocation.enable" : "all"
}
}'

但没有感情。

我该怎么办？感谢先进。

Answer 1

如果你有两个节点，如
1）节点-1 - ES 1.4.2
2）节点-2 - Es 1.1.1

现在按照以下步骤进行调试。

1）从Node-2停止所有elasticsearch实例 2）在新的elasticsearch节点中安装elasticsearch 1.4.2。将elasticsearch.yml更改为主节点配置，特别是这三个配置设置

 cluster.name: <Same as master node>
 node.name: < Node name for Node-2>
 discovery.zen.ping.unicast.hosts: <Master Node IP>

3）重新启动Node-2 Elasticsearch 4）验证节点1日志。

elasticsearch - 删除第二个elasticsearch节点并添加另一个节点，获取未分配的分片
