#Common questions:

##1. Why Spring Boot 1.x.x doesn't work with Elasticsearch 2.x.x?

Spring boot 1.x.x auto configuration is using ImmutableSettings class from Elasticsearch and that class has been removed in version 2.x.x of Elasticsearch.

For more information please look at that page: Breaking changes in Elasticsearch 2.0

##2. Run Spring Boot 1.3.5 + ES 1.7.2

Spring Boot has dedicated module to specify dependency versions. To change version of ES from 1.5.2 to 1.7.2 add elasticsearch.version into your pom properties

<properties>
    ...
    <elasticsearch.version>1.7.2</elasticsearch.version>
    ...
</properties>

##3. Caused by: java.lang.IllegalArgumentException: @ConditionalOnMissingBean annotations must specify at least one bean (type, name or annotation)

You have mixed version of Spring Boot 1.3.5 with ES 2.x.x and this will not work - please look at Point 1.
