elasticsearch失败并显示错误"无法执行阶段[query_fetch],所有分片都失败"

Question

当我尝试索引数据然后进行查询时,一切都很好,但如果我启动我的应用程序并将在没有索引的情况下进行查询之前我得到了该错误

Exception in thread "main" org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to execute phase [query_fetch], all shards failed at org.elasticsearch.action.search.type.TransportSearchTypeAction$BaseAsyncAction.onFirstPhaseResult(TransportSearchTypeAction.java:272)

这是我的弹性搜索的代码和设置

    //  settings
    ImmutableSettings.Builder settings = ImmutableSettings.settingsBuilder();
    settings.put("client.transport.sniff", false);
    settings.put("path.home", "/path/to/elastic/home");
    settings.put("index.number_of_replicas", 0);
    settings.put("index.number_of_shards", 1);
    settings.put("action.write_consistency", "one");

    settings.build();
    // creating of node and client
    NodeBuilder nb = new NodeBuilder().settings(settings).local(true).data(true);
    Node node = nb.node();
    Client client = node.client();


    /*
         for (int i = 0; i <= 15; i++) {
         IndexResponse response = client.prepareIndex("twitter2", "tweet2", String.valueOf(i))
                .setSource(json1)
                .execute()
                .actionGet();
         }
   */

       searchRequestBuilder = client.prepareSearch("twitter2")
            .setTypes("tweet2")
            .setQuery(QueryBuilders.matchQuery("user", "user0"))
            .setQuery(QueryBuilders.matchQuery("message","message1"))
            .setExplain(true)
            .setSearchType(SearchType.DFS_QUERY_AND_FETCH).setSize(200);

        SearchResponse searchRespons = searchRequestBuilder.execute().actionGet(); // here is error

我的设置有什么问题？

您可以在添加睡眠（例如 10 秒后）后尝试相同的操作吗

Client client = node.client();

我觉得 Elasticsearch 在您发出搜索请求之前还没有恢复分片。即使是管理员呼叫“等待黄色”也应该适合您
