我已经存在索引名称test-migrate。我想通过自定义映射将数据添加到其中，以实现父子孙关系。我收到指定索引的解析错误。你能指出我的错误。
curl -XPUT 'http://url:9200/test-migrate'
{"acknowledged":true,"shards_acknowledged":true}
以下是我的映射的样子：
curl -XPUT 'url:9200/test-migrate/type/_mapping' -d '
{
"type" : {
"dynamic": "strict",
"properties" : {
"@timestamp" : {
"type" : "date"
},
"@version" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"sub" : {
"properties" : {
"mnumber" : {
"type" : "long"
},
"pnumber" : {
"type" : "long"
},
"s_id" : {
"type" : "long"
},
"s_name" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
},
"comp": {
"_parent": {
"type" : "sub"
},
"properties" : {
"comp_id" : {
"type" : "long"
},
"comp_name" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
},
"we" : {
"_parent" : {
"type" : "comp"
},
"_routing" : {
"type" : "sub"
},
"properties" : {
"we_1" : {
"type" : "float"
},
"we_2" : {
"type" : "float"
}
}
}
}
}
}
'
但是当我执行它时，我收到一条错误消息：
{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Mapping definition for [comp] has unsupported parameters: [_parent : {type=sub}]"}],"type":"mapper_parsing_exception","reason":"Mapping definition for [comp] has unsupported parameters: [_parent : {type=sub}]"},"status":400}
答案 0 :(得分：0)
这应该有效。结构与映射结构存在问题，其他类型的映射必须定义为单独的映射对象。
PUT parent_index
{
"mappings": {
"type": {
"dynamic": "strict",
"properties": {
"@timestamp": {
"type": "date"
},
"@version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"sub": {
"properties": {
"mnumber": {
"type": "long"

"pnumber": {

"s_id": {

"we": {

注意： 您正在寻找的其他方式。
首先，创建索引
PUT test-migrate
第二次，现在添加类型
的映射POST test-migrate/_mapping/type
{
"type": {
"dynamic": "strict",
"properties": {
"@timestamp": {
"type": "date"
},
"@version": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"sub": {
"properties": {
"mnumber": {
"type": "long"
},
"pnumber": {
"type": "long"
},
"s_id": {
"type": "long"
},
"s_name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
},
"we": {
"_parent": {
"type": "comp"
},
"_routing": {
"type": "sub"
},
"properties": {
"we_1": {
"type": "float"
},
"we_2": {
"type": "float"
}
}
},
"comp": {
"_parent": {
"type": "sub"
},
"properties": {
"comp_id": {
"type": "long"
},
"comp_name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
