CreateIndexRequest indexRequest = new CreateIndexRequest(indexName);  
indexRequest.settings(Settings.builder().put("index.number\_of\_shards", 1));

String jsonst =  
"{\n " +  
" "properties" : {\n" +  
" "syn": {\n" +  
" "type": "text"\n" +  
" }\n" +  
" }\n" +  
"}";  
indexRequest.mapping(jsonst, XContentType.JSON);  
CreateIndexResponse indexResponse = client.indices().create(indexRequest, RequestOptions.DEFAULT);

- error  
mapping source must be pairs of fieldnames and properties definition.

What is the problem?
