ElasticSearch 5：插入数据时出现MapperParserException [英] ElasticSearch 5: MapperParserException while Inserting data

问题描述

我最初的映射是

{
  "vehiclemodel": {
    "properties": {
      "price": {
        "type": "double"
      }
    }
  }
}

后来我用以下内容更新了映射

Later I updated the mapping with below

{
  "vehiclemodel": {
    "properties": {
      "price": {
        "type": "double",
        "fields": {
          "exShowroomPrice": {
            "type": "double"
          }
        }
      }
    }
  }
}

现在，当我添加 Data1 时，它会添加，但是当我添加 Data2 会在异常以下抛出

Now when I add Data1 it getting added, but when I add Data2 it throws below exception

Data1 ：

{
  "price": 36992043     
}

数据2 ：

{
  "price": {
    "exShowroomPrice": 36992043
  }
}

例外：

{
    'index': {
        '_index': 'notes',
        '_type': 'vehiclemodel',
        '_id': 'fb85823a-021b-468c-91d9-8db5f001ee06',
        'status': 400,
        'error': {
            'type': 'mapper_parsing_exception',
            'reason': 'failed to parse [price]',
            'caused_by': {
                'type': 'json_parse_exception',
                'reason': 'Current token (START_OBJECT) not numeric, can not use numeric value accessors\n at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@6e2393ee; line: 1, column: 277]'
            }
        }
    }
}

我的收藏集车辆模型在 MongoDB 中具有两种类型的数据。我正在使用mongo-connector在mongo和ES之间同步数据。当我尝试同步时，出现上述异常

My collectionvehiclemodel has both type of data in MongoDB. I am using mongo-connector to sync data btw mongo and ES. When I try to sync I get the above exception

推荐答案

对于您认为要实现的目标，您的映射不正确。

Your mapping is not correct for what I assume you want to achieve.

字段映射，您可以例如使用不同的分析器为同一字段建立索引（有关详细信息，请参见链接的文档）。因此，在您的情况下，您可以按

The fields mapping allows you to index the same field with different analyzers for example (see the linked docs for details). So in your case, you would push

{
    "price" : 1923
}

，ES会将其存储两次，一次为价格，然后只需在路径 price.exShowroomPrice 下。

and ES will store it twice, once as price and once under the path price.exShowroomPrice.

您只需添加一个完全独立的属性，层次结构就不需要保持。例如这样的映射：

You could just add a completely separate property, the hierarchy does not need to be maintained. For example a mapping like:

{
    "vehiclemodel": {
        "properties": {
            "price": {
                "type": "double"
            },
            "exShowroomPrice": {
                "type": "double"
            }
        }
    }
}

然后像这样发送数据：

{
    "price" : 1923
    "exShowroomPrice" : 1800
} 

我不知道mongo-connector的工作原理，但是应该有一种方法可以映射这些字段会承担。

I don't know how mongo-connector works, but there should be a way to map these fields I would assume.
