NoNodeAvailableException error

Elastic Stack Elasticsearch
1

I am trying to save data in elasticsearch database through REST API using SpringBoot.I am using the following in my application.yml file

  data:
    elasticsearch:
      username: xxxxx
      password: xxxxx
      host: xxxxx
      node-name: xxxxx
      cluster-name: xxxx
      cluster-nodes: localhost:9300
      client:
        transport:
          ignore_cluster_name: true

I am keeping the Config File blank

On running the project I am getting the following logs

main org.elasticsearch.client.transport.TransportClientNodesService - {} - node {#transport#-1}{m-Y19jlaSfOhQNkqjzzDaw}{localhost}{127.0.0.1:9300} not part of the cluster Cluster [xxxxxx], ignoring...

Few comments:

Sure. But you are using the deprecated TransportClient here which is not using the REST Layer (9200) but the Transport Layer (9300).

You should switch to the rest client instead. I guess you are using spring data elasticsearch, so have a look at their documentation on how to switch to the REST Client.

Can you please provide the link to the documentation

A simple google search drove me to https://docs.spring.io/spring-data/elasticsearch/docs/current/reference/html/#elasticsearch.clients.rest

I will not be able to use REST Client as some part of the code fetches data through kafka which would make it very slow. Is there any other alterenartive ?

6

Why do you think so?

I am able to save the data on elasticsearch version locally which runs on localhost:9200 but not on the database on my companies server. My code is what it was at the beginning and I am getting the error while only while using the database in my companie's server.

Is it because it may have a different transport client instead of localhost:9300 ?

8

That's not the same question. Why do you think it will be slow which prevents you using the REST Client?
