1、在Kibana創(chuàng)建索引的時候報錯，使用的elasticsearch版本是7.2.1版本。
1 PUT /person
2 {
3 "settings": {
4 "number_of_shards": "10",
5 "number_of_replicas": "0",
6 "refresh_interval": "-1"
7 },
8 "mappings": {
9 "properties": {
10 "update_time": {
11 "format": "yyyy-MM-dd HH:mm:ss",
12 "type": "date"
13 },
14 "username": {
15 "type": "keyword"
16 },
17 "address": {
18 "type": "keyword"
19 }
20 }
21 }
22 }
報錯，如下所示：
1 {
2 "error": {
3 "root_cause": [{
4 "type": "mapper_parsing_exception",
5 "reason": "Root mapping definition has unsupported parameters: [project_evaluate : {properties={update_time={format=yyyy-MM-dd HH:mm:ss, type=date}, username={type=keyword}, address={type=keyword}}}]"
6 }],
7 "type": "mapper_parsing_exception",
8 "reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [project_evaluate : {properties={update_time={format=yyyy-MM-dd HH:mm:ss, type=date}, username={type=keyword}, address={type=keyword}}}]",
9 "caused_by": {
10 "type": "mapper_parsing_exception",
11 "reason": "Root mapping definition has unsupported parameters: [project_evaluate : {properties={update_time={format=yyyy-MM-dd HH:mm:ss, type=date}, username={type=keyword}, address={type=keyword}}}]"
12 }
13 },
14 "status": 400
15 }
具體原因是ElasticSearch 7.x 默認不在支持指定索引類型。所以在ElasticSearch 7.x中不指定索引類型，創(chuàng)建索引是成功的。
但是對于ElasticSearch 6.x執(zhí)行時沒有問題的，Elasticsearch7默認不在支持指定索引類型，默認索引類型是_doc，索引不再推薦創(chuàng)建索引類型了，使用默認的即可。因為elasticsearch8后就不在提供該字段。
