ElasticSearch bulk 대량 삽입 데이터

환경: Bulk 작업에 RestHighLevelClient 사용
코드는 다음과 같습니다.

/**
     * es         
     * 1.  es clent
     * 2.  bulk   
     * 3. bulk          
     * 4.  rest  
     * 5.  client
     * @throws IOException
     */
public void bulk2() throws IOException {

        int a = 1;
        //    
        RestHighLevelClient restClient = new RestHighLevelClient(
                RestClient.builder(
                        new HttpHost("localhost",9200,"http")
                )
        );


        BulkRequest request = new BulkRequest();

        // source     Map(String,Object)
        request.add(new IndexRequest("index_text","doc","1")
                .source(XContentType.JSON,"name","amy","age",10))
                .add(new IndexRequest("index_text","doc","2")
                .source(XContentType.JSON,"name","bob","age",11));

        restClient.bulk(request);

        restClient.close();

    }

코드에서source () 로 전송되는 매개 변수는 형식일 수도 있습니다

        //   Map(String,Object)   source    
        BulkRequest request2 = new BulkRequest();

        Map jsonMap = new HashMap<>();
        jsonMap.put("name","  ");
        jsonMap.put("age",11);

        request2.add(new IndexRequest("index_text","doc","1")
                .source(jsonMap));
        restClient.bulk(request2);

        //   XContentBuilder   source    
        XContentBuilder builder = new XContentFactory().jsonBuilder();
        builder.startObject();
        {
            builder.field("name","  ");
            builder.timeField("date",new Date());
        }
        builder.endObject();

        BulkRequest request3 = new BulkRequest();
        request3.add(new IndexRequest("index_text","doc","5")
                .source(builder));

원인: 의존이 맞지 않습니다 org.elasticsearch elasticsearch 의존은 로컬es버전과 같기 때문이다(내가 사용한 것은 6.3.1)
