ElasticSearch 7.4.2 Root mapping definition has unsupported parameters

新建索引

PUT people

{
    "settings":{
        "number_of_shards":3,
        "number_of_replicas":1
    },
    "mappings":{
        "man":{
            "properties":{
                "name":{
                    "type":"text"
                },
                "country":{
                    "type":"keyword"
                },
                "age":{
                    "type":"integer"
                },
                "date":{
                    "type":"date",
                    "format":"yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
                }
            }
        }    
    }
}

然后，报错：Root mapping definition has unsupported parameters

查看官网示例后发现 7.4 默认不在支持指定索引类型，默认索引类型是_doc（隐含：include_type_name=false）。见官网：https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html#_typeless_apis_in_7_0

修改：

{
    "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 1
    },
    "mappings": {
        "properties": {
            "name": {
                "type": "text"
            },
            "country": {
                "type": "keyword"
            },
            "age": {
                "type": "integer"
            },
            "date": {
                "type": "date",
                "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
            }
        }
    }
}

 如果你要像之前旧版版本一样兼容自定义 type ,需要将 include_type_name=true 携带， 见官网示例： https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html#_index_templates

PUT localhost:9200/people?include_type_name=true

但是这一字段将在8.x 舍弃
