We are trying to connect to elastic search 2.1.1 version , by creating a client class in spring . Added the required dependencies as folows,

 org.elasticsearch elasticsearch 2.1.1 

```
	<dependency>
		<groupId>org.springframework.data</groupId>
		<artifactId>spring-data-elasticsearch</artifactId>
		<exclusions>
			<exclusion>
				<groupId>org.elasticsearch</groupId>
				<artifactId>elasticsearch</artifactId>
			</exclusion>
		</exclusions>
		<version>1.3.4.RELEASE</version>
	</dependency>

```

The client class is as follows,

@Configuration  
@EnableElasticsearchRepositories(basePackages = "com.abc.test.elasticsearch")  
public class ElasticSearchConfig {

```
 @Bean public ElasticsearchOperations elasticsearchTemplate() { 
	 System.getProperties().setProperty("es.path.home", "C:\\elasticsearch-2.1.1");
	 return new ElasticsearchTemplate(NodeBuilder.nodeBuilder().local(true).node().client()); 
 }

```

}

It's throwing the following exception.

Caused by: java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.yaml.YAMLFactory.\_decorate(Ljava/io/Reader;Lcom/fasterxml/jackson/core/io/IOContext;)Ljava/io/Reader;

Could you please let me know what dependency is missing , or what is wrong with my client class.

I don't think that spring data has been updated to 2.x series.
