Question

我们将elasticsearch集群从2.1.1升级到2.2。我们通过2.1.1之前工作的bulkload处理器的批量加载过程现在抛出以下异常。如果我错过了什么，请告诉我。我是这方面的新手。

测试代码如下：

public class ESTest {

    private static final Logger LOG = LoggerFactory.getLogger(ESTest.class);

    public static void main(String[] args) throws IOException {

        String[] esnodes = "elasticsearch-master-01:9300,elasticsearch-master-02:9300,elasticsearch-master-03:9300"
                .split(",");
        Settings settings = Settings.builder().put("cluster.name", "zuelasticsearch")
                .put("client.transport.sniff", false).put("client.transport.ping_timeout", 20, TimeUnit.SECONDS)
                .build();

        TransportClient tclient = TransportClient.builder().settings(settings).build();
        for (String node : esnodes) {
            String[] host = node.split(":");
            tclient.addTransportAddress(
                    new InetSocketTransportAddress(InetAddress.getByName(host[0]), Integer.valueOf(host[1])));
        }

        Client client = tclient;

        BulkProcessor bulkProcessor = getBulkProcessor(client, 3000, 3);

        String[] strs = { "This", "is", "a", "good", "test" };

        for (int i = 0; i < 100; i++) {

            XContentBuilder jsonBuilder = XContentFactory.jsonBuilder().startObject();
            jsonBuilder.field(String.valueOf(i), strs[i % 5]);
            jsonBuilder.endObject();
            bulkProcessor
                    .add(client.prepareIndex("remtest", "tello", String.valueOf(i)).setSource(jsonBuilder).request());
        }

        bulkProcessor.close();
        client.close();

    }

    public static BulkProcessor getBulkProcessor(Client client, int nActions, int nConcurrentRequests) {
        return BulkProcessor.builder(client, new Listener() {
            public void beforeBulk(long executionId, BulkRequest request) {
                LOG.info("Going to execute new bulk composed of {} actions", request.numberOfActions());
            }

            public void afterBulk(long executionId, BulkRequest request, BulkResponse response) {
                LOG.info("Executed bulk composed of {} actions", request.numberOfActions());
            }

            public void afterBulk(long executionId, BulkRequest request, Throwable failure) {
                LOG.warn("Error executing bulk", failure);
            }

        }).setBulkActions(nActions).setConcurrentRequests(nConcurrentRequests).build();
    }

}

我通过在代码

中添加以下行来解决此问题

bulkProcessor.awaitClose(30L, TimeUnit.SECONDS);

之前

bulkProcessor.close();
client.close();

ElasticSearch Bulkload TransportException：TransportService已关闭，无法发送请求
