[Elasticsearch exception [type=search_phase_execution_exception, reason=all shards failed]]

现象

在做某一次用到elasticsearch的地位位置搜索时，报错：
ElasticsearchStatusException[Elasticsearch exception [type=search_phase_execution_exception, reason=all shards failed]]

我使用的是GeoDistanceQueryBuilder进行ElasticSearch的地理位置搜索以及排序

排查

后来登录到elasticsearch的服务器上去查看错误日志，发现报错如下：
就是说我的location不是geo_point类型的，这个问题也是排查了好久。
问题的原因很简单，是因为我的index是通过IndexRequest自动创建的，会有问题。

例如：

 String string = JSONObject.fromObject(entity).toString();
            IndexRequest indexRequest = new IndexRequest(INDEX).type(DOC).id(INDEX + "_" + entity.getId()).source(string, XContentType.JSON);

            bulkRequest.add(indexRequest);

解决

手工创建，或者通过Java代码创建索引都可以。一定注意，对应mapping的属性的类型一定是geo_point才行

• 这里我换了个索引，position表示位置信息
  # 使用Java手工创建索引

public class CreateElsIndexMain {

    static final String INDEX_NAME = "t_els_mock";

    @Test
    public void test() throws Exception {
        RestHighLevelClient client = new RestHighLevelClient(RestClient.builder(
                new HttpHost(
                        "127.0.0.1",
                        9200,
                        "http"
                )));
        boolean exists = checkExists(client);
        if (exists) {
            deleteIndex(client);
        }
        createIndex(client);

    }

    public static boolean checkExists(RestHighLevelClient client) throws Exception {
        GetIndexRequest existsRequest = new GetIndexRequest();
        existsRequest.indices(INDEX_NAME);
        boolean exists = client.indices().exists(existsRequest, RequestOptions.DEFAULT);
        return exists;
    }

    public static void createIndex(RestHighLevelClient client) throws Exception {
        Settings.Builder setting = Settings.builder().put("number_of_shards", "5").put("number_of_replicas", 1);
        XContentBuilder mappings = JsonXContent.contentBuilder().
                startObject().startObject("properties").startObject("id").field("type", "text").endObject().
                startObject("name").field("type", "keyword").endObject().
                startObject("createTime").field("type", "keyword").endObject().
                startObject("score").field("type","keyword").endObject().
                startObject("longitude").field("type","float").endObject().
                startObject("latitude").field("type","float").endObject().
                startObject("position").field("type","geo_point").endObject().endObject().endObject();
        CreateIndexRequest request = new CreateIndexRequest(INDEX_NAME).settings(setting).mapping("doc",mappings);
        CreateIndexResponse createIndexResponse = client.indices().create(request, RequestOptions.DEFAULT);
        System.out.println(createIndexResponse);
    }


    public static void deleteIndex(RestHighLevelClient client) throws Exception {
        DeleteIndexRequest deleteIndexRequest = new DeleteIndexRequest();//删除索引同样要创建对象接受索引名
        deleteIndexRequest.indices(INDEX_NAME);//传递索引名
        //执行delete方法进行删除；
        AcknowledgedResponse delete = client.indices().delete(deleteIndexRequest, RequestOptions.DEFAULT);
    }

}

Kibana数据

我们可以使用测试数据，将数据放到es中，通过kibana的dev tools查看该索引的数据，如下示例：

添加数据到es的代码

 @Autowired
    private RestHighLevelClient client;

    private static final String INDEX = "t_els_mock";

    String DOC = "doc";

public void addData(){
        BulkRequest bulkRequest = new BulkRequest();
        List<MockLocationEntity> entities = getEntities();
        for (MockLocationEntity entity : entities){
            String string = JSONObject.fromObject(entity).toString();
            IndexRequest indexRequest = new IndexRequest(INDEX).type(DOC).id(INDEX + "_" + entity.getId()).source(string, XContentType.JSON);

            bulkRequest.add(indexRequest);
        }
        try {
            BulkResponse bulk = client.bulk(bulkRequest, RequestOptions.DEFAULT);
            
        } catch (IOException e) {
        }
    }
