ElasticSearch“无法以1:60在VALUE_NULL上获取文本”

在我的某个索引上运行查询时，Elastic上出现错误。ElasticSearch“无法以1:60在VALUE_NULL上获取文本”

{ 
    "error" : { 
    "root_cause" : [ { 
     "type" : "illegal_state_exception", 
     "reason" : "Can't get text on a VALUE_NULL at 1:60" 
    } ], 
    "type" : "search_phase_execution_exception", 
    "reason" : "all shards failed", 
    "phase" : "query", 
    "grouped" : true, 
    "failed_shards" : [ { 
     "shard" : 0, 
     "index" : "someIndexName", 
     "node" : "sfsfd5sdf", 
     "reason" : { 
     "type" : "illegal_state_exception", 
     "reason" : "Can't get text on a VALUE_NULL at 1:60" 
     } 
    } ] 
    }, 
    "status" : 500 
}

我的配置：

{ 
    "cluster_name" : "clusterName", 
    "status" : "green", 
    "number_of_nodes" : 2, 
    "number_of_data_nodes" : 2, 
    "active_primary_shards" : 16, 
    "active_shards" : 32, 
    "relocating_shards" : 0, 
    "initializing_shards" : 0, 
    "unassigned_shards" : 0, 
    "delayed_unassigned_shards" : 0, 
    "number_of_pending_tasks" : 0, 
    "number_of_in_flight_fetch" : 0, 
    "task_max_waiting_in_queue_millis" : 0, 
    "active_shards_percent_as_number" : 100.0 
} 


"version" : { 
    "number" : "2.3.1", 
    "build_hash" : "bd980929010aef404e7cb0843e61d0665269fc39",

    "build_snapshot" : false, 
    "lucene_version" : "5.5.0" 
},

犯规查询例如：

{

     "filtered": { 
      "query": {

        }, 
        "type": "indexed"

      } 
     } 
    }, 
    "size": 0, 
    "aggregations": { 
     "zoom1": { 
      "geohash_grid": {

       "size": 5000, 
       "precision": 7 
      }, 
      "aggs": { 
       "geohash": { 
        "top_hits": { 
         "sort": { 
          "id": { 
           "order": "desc", 
           "ignore_unmapped": true 
          } 
         }, 
         "_source": false, 
         "fielddata_fields": ["id", "coordsField", null], 
         "size": 1 
        } 
       } 
      } 
     } 
    }

}

用Google搜索，但没有找到任何有关。我应该从哪里开始搜索以了解原因？

你可以发布查询吗？ – keety

完成后，查询与在dev中（2.2.1）中测试的查询相同，唯一可能稍微不同的是数据顺序和/或基于[代码片段]（https：//）的映射 –

github.com/elastic/elasticsearch/blob/0f00c14afc8428a2a72c0b766d2171029dc8f6e1/core/src/main/java/org/elasticsearch/common/xcontent/json/JsonXContentParser.java#L85）异常似乎建议尝试将文本转换为'null'值。可能您可以查看easticsearch集群日志以查看消息是否有更多上下文 – keety

的问题是在查询字段中的null：

"fielddata_fields": ["id", "coordsField", null],

"fielddata_fields": ["id", "coordsField"],

在旧版本Elasticsearch的（2.2.1）空被忽略。
