Question

一切正常，然后我重新编制了索引，突然3/5节点开始出错。显然，这也导致我的结果中只有2/3能够正常回归。这仅适用于自定义搜索查询。代码和罐子在事物工作和不事件之间发生了变化。

注意：常规过滤的multi_match搜索查询工作正常。

我试过了：

删除所有索引并重新索引所有数据
停止并启动Elasticsearch
重新编译我的自定义脚本
尝试搜索查询50次以上（Java中的一半和使用CURL的一半）

Pastebin是控制台中出现的错误：http://pastebin.com/1iq3M6fk

正在执行的搜索查询（这已经工作了好几天而且未受影响）：

{
  "query": {
    "custom_score": {
      "query": {
        "multi_match": {
          "query": "italian",
          "fields": [
            "name",
            "tags"
          ]
        }
      },
      "script": "customscript",
      "params": {
        "lat": 40.76405282025,
        "lon": -73.972994269042
      },
      "lang": "native"
    }
  }
}

以下是我在执行上述查询时得到的响应：

{
  "took": 225,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 2,
    "failed": 3,
    "failures": [
      {
        "status": 500,
        "reason": "RemoteTransportException[Failed to deserialize exception response from stream]; nested: TransportSerializationException[Failed to deserialize exception response from stream]; nested: StreamCorruptedException[unexpected end of block data]; "
      },
      {
        "status": 500,
        "reason": "RemoteTransportException[Failed to deserialize exception response from stream]; nested: TransportSerializationException[Failed to deserialize exception response from stream]; nested: StreamCorruptedException[unexpected end of block data]; "
      },
      {
        "status": 500,
        "reason": "RemoteTransportException[Failed to deserialize exception response from stream]; nested: TransportSerializationException[Failed to deserialize exception response from stream]; nested: StreamCorruptedException[unexpected end of block data]; "
      }
    ]
  },
  "hits": {
    "total": 548,
    "max_score": 16.027588,
    "hits": [
      {
        ...
      }
    ]
  }
}

以下是上述查询中使用的自定义脚本（它还有一个工厂）：

import org.elasticsearch.common.Nullable;
import org.elasticsearch.script.ExecutableScript;
import org.elasticsearch.script.NativeScriptFactory;
import org.elasticsearch.script.AbstractDoubleSearchScript;
import org.elasticsearch.index.mapper.geo.GeoPointDocFieldData;

import java.util.Collection;
import java.util.Map;
import java.io.IOException;
import java.lang.Math;

public class CityMapsCustomScript extends AbstractDoubleSearchScript {

    double lat;
    double lon;

    public CityMapsCustomScript(@Nullable Map<String, Object> params) {
        lat = ((Double) params.get("lat")).doubleValue();
        lon = ((Double) params.get("lon")).doubleValue();
    }

    @Override
    public double runAsDouble() {
        double distance = ((GeoPointDocFieldData) doc().field("location")).distance(lat, lon);
        String str = doc().field("_type").getStringValue();
        float score = score();

        if (str.equals("business")) {
            return -distance + (double) score;
        } else {
            return Double.parseDouble(doc().field("_boost").getStringValue());
        }
    }
}

多个节点返回500个错误以进行自定义脚本查询
