Elasticsearch Java API – Get Type List from given Index

The following is sample Java program to get the list of type for a given index name in an Elasticsearch instance.

Sample Program:

package com.report.test;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.ExecutionException;
import org.elasticsearch.action.admin.indices.mapping.get.GetMappingsRequest;
import org.elasticsearch.action.admin.indices.mapping.get.GetMappingsResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.cluster.metadata.MappingMetaData;
import org.elasticsearch.common.collect.ImmutableOpenMap;
import org.elasticsearch.common.hppc.cursors.ObjectObjectCursor;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;

public class SampleProgram{
     public static void main(String[] args) {
          String hostname = "localhost";
          String clusterName = "elasticsearch";

          Settings settings = ImmutableSettings.settingsBuilder().put("client.transport.sniff", true).put("cluster.name", clusterName).build();
          Client esclient = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress(hostname, 9300));

          String index = "game";
          List<String> typeList = new ArrayList<String>();
          try {
               GetMappingsResponse res = esclient.admin().indices().getMappings(new GetMappingsRequest().indices(index)).get();
               ImmutableOpenMap<String, MappingMetaData> mapping = res.mappings().get(index);
               for (ObjectObjectCursor<String, MappingMetaData> c : mapping) {
          } catch (InterruptedException e) {
          } catch (ExecutionException e) {

          System.out.println("Type List:");
          for (String type : typeList) {

Sample Output:

Type List:
