ruby-on-rails - 为什么会出现 Searchkick::ImportError - "type"= >"unavailable_shards_exception", "reason"=> "Primary Shard is not active"？

我在 Rails 5.2.2 中使用 searchkick gem 并尝试通过 rails 控制台索引用户模型。 User.reindex 返回此错误:



这是我的 config/initializers/searchkick.rb 初始化文件:

url = begin
        ENV['ELASTICSEARCH_URL']
      rescue StandardError
        "localhost"
      end

Searchkick.client = Elasticsearch::Client.new(
 hosts:             ["http://#{url}"],
 retry_on_failure:  true,
 transport_options: {
   request: {
     timeout: 450
   }
 }
)

curl -XGET "localhost:9200"的输出

  "name" : "RZdkAgz",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "PG5iZcMnQB677DBW2jStuA",
  "version" : {
    "number" : "6.7.0",

    "build_hash" : "8453f77",
    "build_date" : "2019-03-21T15:32:29.844721Z",
    "build_snapshot" : false,
    "lucene_version" : "7.7.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

curl -XGET "localhost:9200/_cluster/health?pretty"的输出

  "cluster_name" : "elasticsearch",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,

最佳答案

一个原因可能是，该节点刚刚加入集群，但尚未分配任何分片。有关更多信息，请参阅此帖子:Unassigned Shards
