ElasticSearch 7.x 报错:Root mapping definition has unsupported parameters
原因:
ElasticSearch 7.x 默认不在支持指定索引类型
在postman中用以下数据执行put请求:
{"mappings": {
"person" :{
"properties": {
"age": {
"type": "integer"
},
"hobby": {
"type": "text"
},
"mail": {
"type": "text"
},
"name": {
"type": "keyword"
}
}
}
}
}
报错:
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "Root mapping definition has unsupported parameters: [person : {properties={mail={type=text}, name={type=keyword}, age={type=integer}, hobby={type=text}}}]"
}
],
"type": "mapper_parsing_exception",
"reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [person : {properties={mail={type=text}, name={type=keyword}, age={type=integer}, hobby={type=text}}}]",
"caused_by": {
"type": "mapper_parsing_exception",
"reason": "Root mapping definition has unsupported parameters: [person : {properties={mail={type=text}, name={type=keyword}, age={type=integer}, hobby={type=text}}}]"
}
},
"status": 400
}
但是对于ElasticSearch 6.x执行时没有问题的,elasticsearch7默认不在支持指定索引类型,默认索引类型是_doc,如果想改变,则配置include_type_name: true 即可(这个没有测试,官方文档说的,无论是否可行,建议不要这么做,因为elasticsearch8后就不在提供该字段)。官方文档:https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html
所以在ElasticSearch 7.x中不指定索引类型,创建索引是成功的
{"mappings": {
"person" :{
"age": {
"type": "integer"
},
"hobby": {
"type": "text"
},
"mail": {
"type": "text"
},
"name": {
"type": "keyword"
}
}
}
}
