我是同样的错误this questuion。作为这个问题的答案，我正在尝试将正确的 url 设置为 PUT 索引映射，但它不适用于我的实例：

$ cat mapping.json | http PUT myhost:9200/acastest/_mapping

结果：

HTTP/1.1 400 Bad Request
Content-Length: 247
Content-Type: application/json; charset=UTF-8

{
    "error": {
        "reason": "Validation Failed: 1: mapping type is missing;", 
        "root_cause": [
            {
                "reason": "Validation Failed: 1: mapping type is missing;", 
                "type": "action_request_validation_exception"
            }
        ], 
        "type": "action_request_validation_exception"
    }, 
    "status": 400
}

并尝试这样做：

$ cat mapping.json | http PUT myhost:9200/acastest/articles/_mapping

结果：

HTTP/1.1 400 Bad Request
Content-Length: 3969
Content-Type: application/json; charset=UTF-8

{
    "error": {
        "reason": "Root mapping definition has unsupported parameters:  [mappings : {articles={properties={category_en={type=string, index=not_analyzed},blah blah blah", 
        "root_cause": [
            {
                "reason": "Root mapping definition has unsupported parameters:  [mappings : {articles={properties={category_en={type=string, index=not_analyzed}, category_fa={blahblah blah", 
                "type": "mapper_parsing_exception"
            }
        ], 
        "type": "mapper_parsing_exception"
    }, 
    "status": 400
}

弹性搜索配置：

"version": {

    "number": "2.1.1",
    "build_hash": "40e2c53a6b6c2972b3d13846e450e66f4375bd71",
    "build_timestamp": "2015-12-15T13:05:55Z",
    "build_snapshot": false,
    "lucene_version": "5.3.1"

},

我的映射文件是这样的：

{ 
    "mappings": {
            "articles": {
                "properties": {
                    "category_en": {
                        "type": "string",
                        "index": "not_analyzed"
                    },
                    "category_fa": {
                        "type": "string",
                        "index": "not_analyzed"
                    },
                    blah
                    blah
                    blah
                }
            }
        }
}

【问题讨论】：

您需要删除 "mappings" 并在您的 mapping.json 文件的顶层添加 "articles"。

【解决方案1】：

您有两种解决方案：

A.如果你想运行

$ cat mapping.json | http PUT myhost:9200/acastest/articles/_mapping

您需要像这样更改您的 mapping.json 文件：

    { 
        "articles": {
            "properties": {
                "category_en": {
                    "type": "string",
                    "index": "not_analyzed"
                },
                "category_fa": {
                    "type": "string",
                    "index": "not_analyzed"
                },
                blah
                blah
                blah
            }
        }
    }

B.或者您可以保留您的 mapping.json 文件，但随后您需要运行以下命令：

$ cat mapping.json | http PUT myhost:9200/acastest

【解决方案2】：

我的解决方案：

将网址更改为：

http://myhost:9200/acastest/_mapping/articles

将mapping.json 更改为：

{
    "articles": {
        "properties": {
            "category_en": {
                "type": "string",
                "index": "not_analyzed"
            },
            "category_fa": {
                "type": "string",
                "index": "not_analyzed"
            },
            blah
            blah
            blah
        }
    }
}
