创建索引请求映射在弹性搜索中失败

Question

我正在尝试在弹性搜索索引中创建 Join 数据类型，它正在从 kibana 控制台/通过 rest 工作，但是当我尝试以编程方式为索引创建映射时，它失败并出现以下错误，

java.util.concurrent.ExecutionException: RemoteTransportException[[3cfb4e163654][172.17.0.2:9300][indices:admin/create]]; nested: MapperParsingException[Failed to parse mapping [properties]: Root mapping definition has unsupported parameters:  [my_join_field : {type=join, relations={question=answer}}] [my_id : {type=keyword}]]; nested: MapperParsingException[Root mapping definition has unsupported parameters:  [my_join_field : {type=join, relations={question=answer}}] [my_id : {type=keyword}]];

映射：

{
"properties": {
"my_id": {
"type": "keyword"
},
"my_join_field": { 
"type": "join",
"relations": {
"question": "answer" 
}
}
}
}

法典：

public void createIndex(ReIndex indexObject) throws XXXDefinedException {
String index = indexObject.getDestinationIndex();
try {
LOG.info("Initiating the index creation process for the " + index);
CreateIndexRequest request = new CreateIndexRequest(index);
if (!CommonUtils.isEmptyMap(indexObject.getMapping())) {
LOG.info("Index Mapping Available : " + index);
String indexMapping = new GsonBuilder().create().toJson(indexObject.getMapping());
request.source(indexMapping, XContentType.JSON);
}
AcknowledgedResponse indexResponse = client.admin().indices().create(request).get();
client.admin().indices().prepareRefresh().execute().actionGet();
LOG.info("Index is created successfully : " + indexResponse);
} catch (Exception e) {
throw new XXXDefinedException (e);
}
}

其中 inputObject.getMapping(( 具有以下映射：

{"mappings":{"properties":{"my_id":{"type":"keyword"},"my_join_field":{"type":"join","relations":{"question":"answer"}}}}}

Answer 1

您的inputObject.getMapping()不应该具有mapping部分。 您能否从以下方面更改inputObject.getMapping()：

{"mappings":{"properties":{"my_id":{"type":"keyword"},"my_join_field":{"type":"join","relations":{"question":"answer"}}}}}

自

{"properties":{"my_id":{"type":"keyword"},"my_join_field":{"type":"join","relations":{"question":"answer"}}}}

让我知道这是否可行。
