如何解决MapperParsingException:[test]的对象映射尝试解析为对象,但得到了EOF

Question

在ElasicSearch中,我创建了一个索引"test"和下面的映射

{
  "index": {
    "_index": "test",
    "_type": "test"
  },
  "settings": {
    "index.number_of_replicas": 0,
    "index.number_of_shards": 2
  },
  "mappings": {
    "_default_": {
      "date_detection": false
    },
    "test": {
      "properties": {
        "dateModified": {
          "dynamic": "true",
          "properties": {
            "date": {
              "type": "string"
            },
            "time": {
              "type": "string"
            }
          }
        }
      }
    }
  }
}   

索引已成功创建.我给了约会日期

{"index":{"_index":"test","_type":"test"}}
{"dateModified":{"date":"25/05/2015","time":"17:54 IST"}}

记录成功插入.如果我提供如下数据,则会给出错误

{"index":{"_index":"test","_type":"test"}}
    {"dateModified":"25/05/2015"}

那么如何解决这个问题,我读了一些与此问题相关的博客和帖子,但他们没有给出解决这个问题的方法.

Answer 1

要解决此问题,您需要在字段中索引相同类型的值dateModified.它听起来你索引一个文档中的内部元素和下一个文档中的字符串值.

dateModified字段的映射inner object有两个字段,date&time.也是dynamic在索引第一个文档时创建的映射.

第一份文件

{
    "dateModified": {
        "date": "25/05/2015",
        "time": "17:54 IST"
    }
}

第二份文件

{
    "dateModified": "25/05/2015"
}

它清楚地表明您正在尝试为特定字段索引具有不同类型值的文档.弹性搜索不支持.每个字段都应具有唯一的数据类型,并且值也应与映射中定义的值相同.

这导致了问题.不要尝试在不同文档的单个字段中索引不同类型的值.
