The index creating by ElasticSearch(6.8.8) not match the configuration in code?

I hava a cluster of ES with 3 servers.
The version of ES and ik are same 6.8.8.
Dependency of spring boot:


The configuration in code like this:

@Document(indexName = "xx", type = "_doc", shards = 3)

When the project startup,it will create index auto,whih the configuration before,and there are some logs like this :

2022-03-24 16:10:40 [WARN ] [I/O dispatcher 1] o.e.c.RestClient#logResponse:65 - request [PUT http://xxx:9200/xxx/_mapping/_doc?master_timeout=30s&include_type_name=true&timeout=30s] returned 2 warnings: [299 Elasticsearch-6.8.8-2f4c224 "'y' year should be replaced with 'u'. Use 'y' for year-of-era. Prefix your date format with '8' to use the new specifier."],[299 Elasticsearch-6.8.8-2f4c224 "[types removal] Specifying types in put mapping requests is deprecated. To be compatible with 7.0, the mapping definition should not be nested under the type name, and the parameter include_type_name must be provided and set to false."]

also there are logs in ES that can match the configuraton :

[2022-03-24T16:10:39,991][INFO ][o.e.c.m.MetaDataCreateIndexService] [node-35] [xxx] creating index, cause [api], templates [], shards [3]/[1], mappings []
[2022-03-24T16:10:40,187][INFO ][o.e.c.m.MetaDataMappingService] [node-35] [xxx/UWWdI8n1RAe1GVbKMQ1oKQ] create_mapping [_doc]
[2022-03-24T16:10:41,336][INFO ][o.e.c.r.a.AllocationService] [node-35] Cluster health status changed from [YELLOW] to [GREEN] (reason: [shards started [[xxx][1]] ...]).

Then I delete all the indices in Kibaba.

In web page of project,I add a data that will trigger the creating of index in code.Then the index ES created with api is wrong,both the setting and mapping.
Here are the logs :

[2022-03-24T13:56:58,144][INFO ][o.e.c.m.MetaDataCreateIndexService] [node-35] [xxx] creating index, cause [auto(bulk api)], templates [], shards [5]/[1], mappings []
[2022-03-24T13:56:58,314][INFO ][o.e.c.m.MetaDataMappingService] [node-35] [xxx/c-WvlLGmTve5yxxQClvP5w] create_mapping [_doc]
[2022-03-24T13:56:58,858][INFO ][o.e.c.r.a.AllocationService] [node-35] Cluster health status changed from [YELLOW] to [GREEN] (reason: [shards started [[patient][4]] ...]).

The one is cause(api) and another is cause(auto(bulk api)).

What should I do?

Welcome to our community! :smiley:

6.8 is EOL and no longer supported, you need to upgrade ASAP. Latest is 8.1.

Do they make the same requests to Elasticsearch?
