Hello,

I have a mapping.json file and want to add another field to it using PUT Mapping API.

I am using the below mentioned code :=\>

```auto
try {
            jsonDocMapping = XContentFactory.jsonBuilder()
                    
                    .startObject("docs")
                        .startObject("properties")
                            .startObject("MY_FIELD")
                                .field("type", "string")
                                .field("analyzer", "shingleAnalyzer")
                                .startObject("fields")
                                    .startObject("raw_standard_analyzer")
                                        .field("type","string")
                                    .endObject()
                                .endObject()
                            .endObject()
                        .endObject()
                    .endObject()
             ;
            map.source(jsonDocMapping).type();
        
    PutMappingResponse mapp = ESclient.admin().indices().putMapping(map).actionGet();
        
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

```

But I execute I face the following error :

```auto
Exception in thread "main" org.elasticsearch.action.ActionRequestValidationException: Validation Failed: 1: mapping type is missing;
    at org.elasticsearch.action.ValidateActions.addValidationError(ValidateActions.java:29)

```

You need to add `.setType("docs")`.

```auto
PutMappingResponse mapp = ESclient.admin().indices().setType("docs").putMapping(map).actionGet();

```

That might help you.
