java.lang.IllegalStateException: Received message from unsupported version: [2.0 .0] minimal compatible version is: [5.0.0]

Question

I'm trying to do this sample tutorial, in order to get familiar with elasticsearch. but running the project it gives this error in intellij:

org.elasticsearch.transport.NodeDisconnectedException: [][127.0.0.1:9300][cluster:monitor/nodes/liveness] disconnected

and in the elasticsearch.bat it gives this error:

I searched and it's said that it's maybe conflict between spring boot and elasticsearch version. but in the pom file of that tutorial version of elastic search isn't specified:

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.2.RELEASE</version>
    </parent>

            <!--<version>1.13.3.RELEASE</version>-->
        <!--</dependency>-->

    </dependencies>

is the problem of confliction of versions and how can I solve it?

Answer 1

Take a look at my Github repository. It works with an instance of Elasticsearch version 2.4.6.

Unfortunately, Spring Boot Starter Data Elasticsearch does not support Elasticsearch version 5.x yet, they are working on it, but you can use my repository just changing the model propertly and update the repository with your own methods.

Your error is because you are using an instance of Elasticsearch 5.x and you need a 2.x version.

Answer 2

Spring doesn't support latest versions of elasticsearch client. You can refer to the following github repo for version compatibility
