Я использовал следующий код для создания индекса в Elastic Search, API JAVA по умолчанию:
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "myClusterName").put("client.transport.sniff", true).build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate("test1");
CreateIndexResponse response = createIndexRequestBuilder.execute().actionGet();
System.out.println(response.isAcknowledged());
Служба REST:
HttpURLConnection con = null;
try
{
String url = "http://localhost:9200/test2";
URL resturl = new URL(url);
con = (HttpURLConnection) resturl.openConnection();
con.setDoOutput(true);
con.setRequestMethod("PUT");
BufferedReader in = null;
try
{
if (con.getInputStream() != null)
{
in = new BufferedReader(new InputStreamReader(con.getInputStream()));
}
}
catch (IOException e)
{
if (con.getErrorStream() != null)
{
in = new BufferedReader(new InputStreamReader(con.getErrorStream()));
}
}
if (in == null)
{
throw new Exception("Unable to read response from server");
}
StringBuffer decodedString = new StringBuffer();
String line;
while ((line = in.readLine()) != null)
{
decodedString.append(line);
}
in.close();
System.out.println("4");
Integer responseCode = con.getResponseCode();
System.out.println(responseCode);
}
catch (Exception ex)
{
ex.printStackTrace();
}
finally
{
if (con != null)
{
con.disconnect();
}
}
Используя REST API, я могу создать индекс. По умолчанию JAVA API, Я получаю следующее исключение.

Прошу вас, если я ошибаюсь. Спасибо заранее
