Elasticsearch doesn't initialize in Spring Boot

Question

I am updating the spring boot version of my applications to a version, in case I was using version 1.3.2 I am now migrating to 1.4.3. So my Elasticsearch is giving the following error.

2017-06-01 10:41:28.449  WARN 12480 --- [ I/O worker #1}] org.elasticsearch.transport.netty        : [Maxam] exception caught on transport layer [[id: 0x12666e2c, /192.168.1.9:63584 => /XXX.XXX.XXX.XXX:9300]], closing connection

Check that all elasticsearch instances (nodes) are shutdown and restart your app. See this issue in ES github.com/elastic/elasticsearch/issues/14400 — Issam El-atif

You should use ES from 2.0.0 to 5.0.0 . See github.com/spring-projects/spring-data-elasticsearch/wiki/… — Issam El-atif

Spring-boot:1.4.3 is not compatible with elasticsearch 1.x versions hence it has a dependency on spring-data-elasticsearch:2.0.6.RELEASE.

You should use elasticsearch version between 2.0.0 and 5.0.0. See Spring Data Elasticsearch Spring Boot version matrix
