Question

我创建了一个包含2个节点的ES群集。其中一个节点配置为主节点，另一个节点配置为客户端节点。主节点具有完全构建的索引。

当我在其余客户端上运行以下内容时 http://localhost:9200/_cluster/health，我收到以下回复

{
    "cluster_name": "827d89539ac6ae688c1a84b9a7076b33",
    "status": "green",
    "timed_out": false,
    "number_of_nodes": 2,
    "number_of_data_nodes": 1,
    "active_primary_shards": 4,
    "active_shards": 4,
    "relocating_shards": 0,
    "initializing_shards": 0,
    "unassigned_shards": 0
}

这表明客户端节点已加入群集。

我能够从主节点进行搜索和索引。但是在尝试从客户端节点搜索时，我得到以下异常。

Caused by: org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to execute phase [query_fetch], all shards failed; shardFailures {[FI4lBsqZSne3MzDY5QLDvw][rule][0]: RemoteTransportException[Failed to deserialize response of type [org.elasticsearch.search.fetch.QueryFetchSearchResult]]; nested: TransportSerializationException[Failed to deserialize response of type [org.elasticsearch.search.fetch.QueryFetchSearchResult]]; nested: IOException[Expected handle header, got [90]]; }

我用来连接主节点的设置是

ImmutableSettings.Builder settingsBuilder = ImmutableSettings.settingsBuilder()
            //.classLoader(getClass().getClassLoader()) // set the class loader to PRAppLoader
            .put("cluster.name", "827d89539ac6ae688c1a84b9a7076b33")
            .put("node.name", "wkoduyw7hyd")
            .put("node.master", false)
            .put("node.data", false)
            .put("action.auto_create_index", false) // disable automatic index creation
            .put("script.disable_dynamic", true) // disable dynamic scripts
            .put("script.auto_reload_enabled" , false) // disable script reloading
            .put("path.data", "H:\\WorkSpace\\LunaSprintWorks_Trunc\\miniboot-embedded\\local_8084\\Tomcat\\work\\Catalina\\localhost\\prweb\\PegaSearchIndex")
            ;
    settingsBuilder.put("discovery.zen.ping.multicast.enabled", true);
    settingsBuilder.put("threadpool.index.size", 1);
    settingsBuilder.put("threadpool.search.size", 1);
    settingsBuilder.put("threadpool.bulk.size", 1);
    settingsBuilder.put("threadpool.suggest.size", 1);
    settingsBuilder.put("threadpool.get.size", 1);
    settingsBuilder.put("threadpool.percolate.size", 1);
    settingsBuilder.put("transport.netty.worker_count", 2);
    settingsBuilder.put("http.netty.worker_count", 1);

我在客户端节点中执行的搜索查询在其余客户端上正常工作。

我从queryBuilders构造的查询是

＆＃13;

{
  "query" : {
    "filtered" : {
      "query" : {
        "query_string" : {
          "query" : "pxRetrieveReportData",
          "default_field" : "_instancename",
          "default_operator" : "and",
          "allow_leading_wildcard" : true,
          "analyze_wildcard" : true
        }
      },
      "filter" : {
        "fquery" : {
          "query" : {
            "query_string" : {
              "query" : "NOT _isexternal:true",
              "default_field" : "_instancename",
              "default_operator" : "and",
              "allow_leading_wildcard" : true
            }
          },
          "_cache" : false
        }
      }
    }
  },
  "fields" : "*"
}

＆＃13;

您能告诉我们在哪些情况下我们会遇到此异常吗？

我在两个节点中使用相同版本的elasticsearch jar。

Answer 1

该异常是可能在客户端和群集之间使用混合Elasticsearch版本的标志。

从连接到ElasticSearch Cluster
