[英]NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{XY6cYmf7Sn-DRZgzeq3PBA}{localhost}{127.0.0.1:9300}]]
I am using BULK API of elasticsearch with version 5.6.16 of Elasticsearch and KIbana both.我正在使用 elasticsearch 的 BULK API 和 Elasticsearch 和 KIbana 的 5.6.16 版本。 The following code is working fine and uploading the code to an index of ES.
以下代码工作正常并将代码上传到 ES 的索引。
these are dependencies that I currently have.这些是我目前拥有的依赖项。
implementation 'org.springframework.boot:spring-boot-starter-data-elasticsearch'
实施 'org.springframework.boot:spring-boot-starter-data-elasticsearch'
compile group: 'org.elasticsearch.client', name: 'transport'
编译组:'org.elasticsearch.client',名称:'transport'

@Service
public class BulkApiService {
private final Logger log = LoggerFactory.getLogger(BulkApiService.class);
private String FOLDER_PATH = "src/main/resources/allRecipesJson";
private String index = "test";
@Autowired
ElasticSearchConfig elasticSearchConfig;
public String loadBulkData() throws UnknownHostException {
Client client = elasticSearchConfig.client();
AtomicReference<BulkRequestBuilder> request = new AtomicReference<>(client.prepareBulk());
AtomicInteger counter = new AtomicInteger();
try (Stream<Path> filePathStream = Files.walk(Paths.get(FOLDER_PATH))) {
filePathStream.forEach(filePath -> {
if (Files.isRegularFile(filePath)) {
counter.getAndIncrement();
try {
String content = Files.readString(filePath);
JSONObject jsonObject1 = new JSONObject(content);
HashMap yourHashMap1 = new Gson().fromJson(jsonObject1.toString(), HashMap.class);
request.get().add(client.prepareIndex(index, "default").setSource(yourHashMap1));
} catch (IOException ignore) {
log.error(ignore.toString());
}
}
});
BulkResponse bulkResponse = request.get().execute().actionGet();
} catch (Exception e) {
log.error(e.toString());
}
return "Bulk data loaded to index " + index + "";
}
Following is the configuration以下是配置
@Configuration
public class ElasticSearchConfig {
private static final Logger log = LoggerFactory.getLogger(ElasticSearchConfig.class);
@Bean
public Client client() {
TransportClient client = null;
try {
client = new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300));
} catch (UnknownHostException e) {
log.error(log.toString());
}
return client;
}
}
Now I want to move to Elasticserch and Kibana version 7.3.1.现在我想迁移到 Elasticserch 和 Kibana 版本 7.3.1。 I am unable to load the data to the elasticsearch index.
我无法将数据加载到 elasticsearch 索引。 The following error is shown on IDE Log
IDE 日志显示以下错误
service.BulkApiService - NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{XY6cYmf7Sn-DRZgzeq3PBA}{localhost}{127.0.0.1:9300}]]
service.BulkApiService - NoNodeAvailableException[配置的节点都不可用:[{#transport#-1}{XY6cYmf7Sn-DRZgzeq3PBA}{localhost}{127.0.0.1:9300}]]
The error on elasticsearch imagec elasticsearch imagec 上的错误
Kindly help me to correct it.请帮我纠正它。
Following is the correct code.以下是正确的代码。
@Service
public class BulkApiService { private final Logger log = LoggerFactory.getLogger(BulkApiService.class);
private String FOLDER_PATH = "src/main/resources/allRecipesJson";
private String index = "test1";
private static final String TYPE = "test_type";
@Autowired
private RestHighLevelClient restHighLevelClient;
public String loadBulkData() throws IOException {
BulkRequest bulkRequest = new BulkRequest();
AtomicInteger counter = new AtomicInteger();
try (Stream<Path> filePathStream = Files.walk(Paths.get(FOLDER_PATH))) {
filePathStream.forEach(filePath -> {
if (Files.isRegularFile(filePath)) {
counter.getAndIncrement();
System.out.println(filePath.toFile().getAbsoluteFile().toString());
try {
String content = Files.readString(filePath);
JSONObject jsonObject1 = new JSONObject(content);
HashMap yourHashMap1 = new Gson().fromJson(jsonObject1.toString(), HashMap.class);
IndexRequest indexRequest = new IndexRequest(index, TYPE).source(yourHashMap1);
bulkRequest.add(indexRequest);
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
try {
restHighLevelClient.bulk(bulkRequest, RequestOptions.DEFAULT);
} catch (IOException e) {
e.printStackTrace();
}
return "Bulk data loaded to index " + index + "";
}
}
Add the following dependency and remove the already placed dependencies.添加以下依赖项并删除已放置的依赖项。
compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.4.2'
编译'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.4.2'
