ElasticSearch 非法参数异常

Question

我在 Ubuntu 16.04 上使用 Elasticsearch 最新版本，但在将数据放入其中时遇到了一些小问题。

这是我的 json 文档(相关部分)

{   "products" : {
    "232CDFDW89ENUXRB" : {
        "sku" : "232CDFDW89ENUXRB",
        "productFamily" : "Compute Instance",
        "attributes" : {
            "servicecode" : "AmazonEC2",
            "location" : "US East (N. Virginia)",
            "locationType" : "AWS Region",
            "instanceType" : "d2.8xlarge",
            "currentGeneration" : "Yes",
            "instanceFamily" : "Storage optimized",
            "vcpu" : "36",
            "physicalProcessor" : "Intel Xeon E5-2676v3 (Haswell)",
            "clockSpeed" : "2.4 GHz",
            "memory" : "244 GiB",
            "storage" : "24 x 2000 HDD",
            "networkPerformance" : "10 Gigabit",
            "processorArchitecture" : "64-bit",
            "tenancy" : "Host",
            "operatingSystem" : "Linux",
            "licenseModel" : "No License required",
            "usagetype" : "HostBoxUsage:d2.8xlarge",
            "operation" : "RunInstances",
            "enhancedNetworkingSupported" : "Yes",
            "preInstalledSw" : "NA",
            "processorFeatures" : "Intel AVX; Intel AVX2; Intel Turbo" }
        }
    }   
}

这是当我尝试“PUT http://localhost:9200/aws”时来自 ES 的返回响应

{ "error": {
"root_cause": [
  {
    "type": "illegal_argument_exception",
    "reason": "unknown setting [index.products.232CDFDW89ENUXRB.attributes.clockSpeed] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"
  }
],
"type": "illegal_argument_exception",
"reason": "unknown setting [index.products.232CDFDW89ENUXRB.attributes.clockSpeed] please check that any required plugins are installed, or check the breaking changes documentation for removed settings" }, "status": 400 }

在我看来，ES 认为“clockSpeed”是某种设置...？我希望使用动态映射来加快处理速度，而不是先映射所有文档，然后再将其导入 ES。
有什么建议吗？

Answer 1

问题是您在通过 PUT http://localhost:9200/aws 索引文档时缺少 document type 和 document id命令。

索引文档的正确方法是:

POST my-index/my-type/my-id-1
{
  "name": "kibana"
}

即您必须提供文档类型(此处为 my-type)和文档 ID(此处为 my-id-1)。请注意，此处的文档 ID 是可选的，因此如果您不提供，则 elasticsearch 会为您创建一个字母数字 ID。

索引文档的其他几种方法:

POST my-index/my-type
{
  "name": "kibana"
}

//if you want to index document through PUT then you must provide document id
PUT my-index/my-type/my-id-1
{
  "name": "kibana"
}

注意:如果自动创建索引被禁用，那么您必须在索引文档之前创建索引。
