elasticsearch - 试图在Elasticsearch中为py-image-dedup定义索引

Question

我正在尝试使py-image-dedup(https://github.com/markusressel/py-image-dedup)工作，这需要在Elasticsearch中建立索引。到目前为止，到目前为止，所有用于py-image-dedup和brew install elasticsearch的python代码都已安装并与Elasticsearch服务器一起工作，并在本地主机地址127.0.0.1:9200上愉快地工作

所以现在我尝试建立索引。指示说

curl -X PUT "127.0.0.1:9200/images?pretty" -H "Content-Type: application/json" -d "
{
  \"mappings\": {
    \"image\": {
      \"properties\": {
        \"path\": {
          \"type\": \"keyword\",
          \"ignore_above\": 256
        }
      }
    }
  }
}

显然在结尾缺少“”，据我所知，它在任何变体中均不起作用。

我尝试

curl -X PUT "127.0.0.1:9200/images?pretty"  -H "Content-Type: application/json" -d "{\"mappings\":{\"image\":{\"properties\":{\"path\":{\"type\":\"keyword\",\"ignore_above\":256}}}}} "

这看起来很明智，但得到

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Root mapping definition has unsupported parameters:  [image : {properties={path={ignore_above=256, type=keyword}}}]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:  [image : {properties={path={ignore_above=256, type=keyword}}}]",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "Root mapping definition has unsupported parameters:  [image : {properties={path={ignore_above=256, type=keyword}}}]"
    }
  },
  "status" : 400
}

我一生都无法看到为什么索引构建不正确。感谢帮助。

您正在尝试使用已过时的类型:https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html

请从您的映射定义中删除image类型。

curl -X PUT "127.0.0.1:9200/images?pretty" -H "Content-Type: application/json" -d "
{
  \"mappings\": {
    \"properties\": {
      \"path\": {
        \"type\": \"keyword\",
        \"ignore_above\": 256
      }
    }
  }
}
