问题描述
我们当前正在使用searchkick gem，它的效果很好.最近，我尝试在本地开发环境中将elasticsearch升级到7.我使用自制软件启动并运行它(研究后我需要运行 rm -fr/usr/local/var/lib/elasticsearch ).当我为一个模型重新索引时，出现以下映射错误:
We are currently using the searchkick gem and it works great. Recently I tried upgrading elasticsearch to 7 in my local development environment. I got it up and running using homebrew ( after researching that I needed to run rm -fr /usr/local/var/lib/elasticsearch). When I went to reindex one of my models I got the following mapping error:
Elasticsearch :: Transport :: Transport :: Errors :: BadRequest:[400] {错误":{"root_cause":[{类型":"mapper_parsing_exception"，原因":根映射定义具有不受支持的参数:[化妆品/产品:{属性= {产品= {类型=关键字}}}}]]"类型":"mapper_parsing_exception"，原因":无法解析映射[_doc]:根映射定义具有不受支持的参数:[化妆品/产品:{properties = {product = {type = keyword}}}]，" caused_by:{" type:" mapper_parsing_exception，"原因:"根映射定义不受支持参数:[化妆品/产品:{属性= {产品= {类型=关键字}}}}}，状态":400}
使用elasticsearch 6.8.4时不会发生此错误.谁能指出我解决该问题的资源?
This error does not occur when using elasticsearch 6.8.4. Can anyone point to me to a resource for resolving this issue?
推荐答案
版本7不支持映射类型.
要解决此问题，请删除所有映射类型(例如_doc)
Mapping type is not supported in version 7.
To solve this, remove all mapping types (_doc for example)
在Elasticsearch 6.0.0或更高版本中创建的索引只能包含一个映射类型.在5.x中创建的具有多种映射类型的索引将继续像在Elasticsearch 6.x中一样工作.类型将在Elasticsearch 7.0.0中的API中弃用，并在8.0.0中完全删除.
