Hi all , i met a weird issue , when i use JSON type XContentBuilder to create index's mapping ,it always return "Failed to close the XContentBuilder Caused by: java.io.IOException: Unclosed object or array found  
at org.elasticsearch.common.xcontent.json.JsonXContentGenerator.close(JsonXContentGenerator.java:469)  
at org.elasticsearch.common.xcontent.XContentBuilder.close(XContentBuilder.java:1000)  
... 36 common frames omitted".

This is the code :

private XContentBuilder getMappingBuilder() throws IOException {  
XContentBuilder builder = XContentFactory.jsonBuilder()  
.startObject()  
.startObject("properties")  
.startObject("@timestamp").field("type", "date")  
.startObject("timestamp").field("format", Constants.DateFormatSuper).field("type", "date")  
.endObject()  
.startObject("nation")  
.field("type", "keyword")  
.endObject()  
.startObject("app")  
.field("type", "keyword")  
.endObject()  
.startObject("order\_no")  
.field("type", "keyword")  
.endObject()  
.startObject("loan\_type")  
.field("type", "keyword")  
.endObject()  
.startObject("loan\_scenario")  
.field("type", "keyword")  
.endObject()  
.startObject("product\_type")  
.field("type", "keyword")  
.endObject()  
.startObject("installments").field("type", "integer").endObject()  
.startObject("platform")  
.field("type", "keyword")  
.endObject()  
.startObject("amount").field("type", "double").endObject()  
.startObject("latitude").field("type", "double").endObject()  
.startObject("longitude").field("type", "double").endObject()  
.startObject("location")  
.field("type", "text")  
.startObject("fields")  
.startObject("raw")  
.field("type", "keyword")  
.endObject()  
.endObject()  
.endObject()  
.startObject("geohash")  
.field("type", "geo\_point")  
.endObject()  
.startObject("city\_geohash")  
.field("type", "geo\_point")  
.endObject()  
.endObject()  
.endObject();  
return builder;  
}

restHighLevelClient.indices().create(new CreateIndexRequest(indexName).mapping(getMappingBuilder())  
.settings(Settings.builder()  
.put("index.number\_of\_shards", shards)  
.put("index.number\_of\_replicas", replicas))  
, RequestOptions.DEFAULT);

You have 20 startObject() and 19 endObject(), which is probably the reason that "IOException: Unclosed object ".
