elasticsearch5.5.1 update mapping

今天发现在5.5.1版本下修改字段mapping添加fielddata:true参数 一直报错提示不支持,5.4版本都没有问题,不知问题何在.求科普;
 
 
拿id字段来说 原来mapping定义如下:

 "id":{

      "type":"long",

       "index":"not_analyzed",

                   

  }

按id排序时提示,需要设置fielddata=true,所以准备更新字段mapping如下:

 curl -XPOST "http://127.0.0.1/test/test/_mapping?pretty" -d '{

     "test": {

                "properties": {

                "id":{

                    "type":"long",

                    "index":"not_analyzed",

                    "fielddata":true

               }

            }

        }

}'

 
结果:

{

  "error" : {

    "root_cause" : [

      {

        "type" : "mapper_parsing_exception",

        "reason" : "Mapping definition for [id] has unsupported parameters:  [fielddata : true]"

      }

    ],

    "type" : "mapper_parsing_exception",

    "reason" : "Mapping definition for [id] has unsupported parameters:  [fielddata : true]"

  },

  "status" : 400

}
