Update mapping API

A PutMappingRequest requires an index argument:

PutMappingRequest request = new PutMappingRequest("twitter"); 

A description of the fields to create on the mapping; if not defined, the mapping will default to empty.

request.source(
    "{\n" +
    "  \"properties\": {\n" +
    "    \"message\": {\n" +
    "      \"type\": \"text\"\n" +
    "    }\n" +
    "  }\n" +
    "}", 
    XContentType.JSON);

The mapping source can be provided in different ways in addition to the String example shown above:

Map<String, Object> jsonMap = new HashMap<>();
Map<String, Object> message = new HashMap<>();
message.put("type", "text");
Map<String, Object> properties = new HashMap<>();
properties.put("message", message);
jsonMap.put("properties", properties);
request.source(jsonMap); 

XContentBuilder builder = XContentFactory.jsonBuilder();
builder.startObject();
{
    builder.startObject("properties");
    {
        builder.startObject("message");
        {
            builder.field("type", "text");
        }
        builder.endObject();
    }
    builder.endObject();
}
builder.endObject();
request.source(builder); 

The following arguments can optionally be provided:

request.setTimeout(TimeValue.timeValueMinutes(2)); 

request.setMasterTimeout(TimeValue.timeValueMinutes(1)); 

When executing a PutMappingRequest in the following manner, the client waits for the PutMappingResponse to be returned before continuing with code execution:

AcknowledgedResponse putMappingResponse = client.indices().putMapping(request, RequestOptions.DEFAULT);

Synchronous calls may throw an IOException in case of either failing to parse the REST response in the high-level REST client, the request times out or similar cases where there is no response coming back from the server.

In cases where the server returns a 4xx or 5xx error code, the high-level client tries to parse the response body error details instead and then throws a generic ElasticsearchException and adds the original ResponseException as a suppressed exception to it.

Executing a PutMappingRequest can also be done in an asynchronous fashion so that the client can return directly. Users need to specify how the response or potential failures will be handled by passing the request and a listener to the asynchronous put-mapping method:

client.indices().putMappingAsync(request, RequestOptions.DEFAULT, listener); 

The asynchronous method does not block and returns immediately. Once it is completed the ActionListener is called back using the onResponse method if the execution successfully completed or using the onFailure method if it failed. Failure scenarios and expected exceptions are the same as in the synchronous execution case.

A typical listener for put-mapping looks like:

ActionListener<AcknowledgedResponse> listener =
    new ActionListener<AcknowledgedResponse>() {
        @Override
        public void onResponse(AcknowledgedResponse putMappingResponse) {
            
        }

        @Override
        public void onFailure(Exception e) {
            
        }
    };

The returned PutMappingResponse allows to retrieve information about the executed operation as follows:

boolean acknowledged = putMappingResponse.isAcknowledged();
