Elasticsearch version 8.1.3 Java version 1.8
Im trying to connect elasticsearch with Java springboot program. My Elasticsearch works fine until I run the Java program, also my java program works fine but with “.d.e.r.s.AbstractElasticsearchRepository : failed to load elasticsearch nodes : org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{LsJSQJtCS56wr7IM_S0h4Q}{localhost}{127.0.0.1:9300}]” on springboot error. Also, as soon as I run my program as java application elasticsearch stops working with “[WARN ][o.e.x.c.s.t.n.SecurityNetty4Transport] [DESKTOP-ADQ0I0S] received plaintext traffic on an encrypted channel, closing connection Netty4TcpChannel{localAddress=/127.0.0.1:9300, remoteAddress=/127.0.0.1:59255, profile=default}“

Error I get on elasticsearch terminal as soon as I run the Java program

To access Elasticsearch with Java I have followed this YouTube video tutorial [1]: https://www.youtube.com/watch?v=dlChXjE7IHw&t=541s
Also, im not able to add the type and shards parameter in the @Document annotation in my model. it is only accepting
@Document(indexName= "myindex")
According to the video it should be
@Document(indexName= "myindex" type="customer", shards=2)
elasticsearch.yml file

Answer
I was using transport client 9300 which is deprecated in Elasticsearch 7 and not supported in version 8 and I was using version 8.1.3. Here we can use the supported Elastic version 7.x or use Elasticsearch Java API client. [Elasticsearch Java API Client 8.1.3] Elasticsearch Java API Client 8.1.3
