Managing mappings

After creating an index, the next step is to add some mapping to it. We have already seen how to apply a mapping via the REST API in Chapter 4, Basic Operations. In this recipe, we will see how to manage mappings via a native client.

Getting ready

You will need a working ElasticSearch cluster and a working copy of Maven.

The code of this recipe is in chapter_10/nativeclient in the code bundle of this book, available on Packt's website, and on GitHub (https://github.com/aparo/elasticsearch-cookbook-second-edition). The referred class is MappingOperations.

How to do it...

The following steps show how to add a mytype mapping to a myindex index via a native client:

   import org.elasticsearch.action.admin.indices.mapping.put. PutMappingResponse;
   import org.elasticsearch.client.Client;
   import org.elasticsearch.common.xcontent.XContentBuilder;
   import java.io.IOException;
   import static org.elasticsearch.common.xcontent.XContentFactory. jsonBuilder;
