Elasticsearch 2.2.0 ESIntegTestCase：sureYellow（）導致“等待黃色的超時”

Question

我正在重寫我們的集成測試以與Elasticsearch 2.2.0一起使用。 我有一個擴展org.elasticsearch.test.ESIntegTestCase的抽象測試用例類：

@ESIntegTestCase.ClusterScope(scope = ESIntegTestCase.Scope.SUITE, numDataNodes = 1)
@ThreadLeakScope(ThreadLeakScope.Scope.NONE)
public abstract class AbstractApplicationTest extends ESIntegTestCase {
   ...

    @Override
    protected Settings nodeSettings(int nodeOrdinal) {
        return Settings.settingsBuilder()
                .put(super.nodeSettings(nodeOrdinal))
                .put(IndexMetaData.SETTING_NUMBER_OF_SHARDS, 1)
                .put(IndexMetaData.SETTING_NUMBER_OF_REPLICAS, 1)
                .put(Node.HTTP_ENABLED, true)
                .put("script.groovy.sandbox.enabled", true)
                .put("script.engine.groovy.inline.search", true)
                .put("script.engine.groovy.inline.update", "true")
                .put("script.inline", true)
                .put("script.update", true)
                .put("script.indexed", true)
                .put("script.default_lang", "groovy")
                .build();
    }

    @Override
    protected Collection<Class<? extends Plugin>> nodePlugins() {
        return pluginList(GroovyPlugin.class, DeleteByQueryPlugin.class, AnalysisICUPlugin.class);
    }

    @Before
    public void setUpElastic() throws Exception {
        // add the index and the mappings
        prepareCreate("bokun")
                .setSettings(Settings.builder().loadFromSource(loadFromClasspath("indices/settings.json")))
                .addMapping(AccommodationSearchIndex.INDEX_ACCOMMODATION_TYPE, loadFromClasspath("indices/accommodation.json"))
                .addMapping(AccommodationSearchIndex.INDEX_ROOM_TYPE, loadFromClasspath("indices/room.json"))
                ...
                .execute().actionGet();
        ensureYellow();
    }
    ...
}

我的測試用例類擴展了這個抽象類。 它有6個測試，在上述的ensureYellow()調用過程中，其中3-4個不斷失敗，並顯示“超時，等待黃色”消息。

如果我注釋掉ensureYellow()調用，那么在執行索引請求時，我將從Elasticsearch中獲取“ unavailable_shards_exception”：

{
    "took": 60001,
    "errors": true,
    "items": [{
        "index": {
            "_index": "bokun",
            "_type": "activity_availability",
            "_id": "20_20160309",
            "status": 503,
            "error": {
                "type": "unavailable_shards_exception",
                "reason": "[bokun][2] primary shard is not active Timeout: [1m], request: [shard bulk {[bokun][2]}]"
            }
        }
    }, {
        "index": {
            "_index": "bokun",
            "_type": "activity_availability",
            "_id": "20_20160310",
            "status": 503,
            "error": {
                "type": "unavailable_shards_exception",
                "reason": "[bokun][1] primary shard is not active Timeout: [1m], request: [shard bulk {[bokun][1]}]"
            }
        }
    }, 
    ...
    {
        "index": {
            "_index": "bokun",
            "_type": "activity_availability",
            "_id": "20_20160322",
            "status": 503,
            "error": {
                "type": "unavailable_shards_exception",
                "reason": "[bokun][0] primary shard is not active Timeout: [1m], request: [shard bulk {[bokun][0]}]"
            }
        }
    }, {
        "index": {
            "_index": "bokun",
            "_type": "activity",
            "_id": "12",
            "status": 503,
            "error": {
                "type": "unavailable_shards_exception",
                "reason": "[bokun][2] primary shard is not active Timeout: [1m], request: [shard bulk {[bokun][2]}]"
            }
        }
    }]
}

測試用例范圍是ESIntegTestCase.Scope.SUITE ，這意味着將為每個SUITE而不是測試創建一個集群，然后在每個測試之前創建索引並添加映射。 我假設每次測試后都會刪除索引，因為此頁面指出：

默認情況下，每個測試套件使用唯一的群集運行測試。 當然，每次測試之間都將刪除所有索引和模板。

有人知道我在這里做錯了嗎？

PS我正在使用SBT來運行測試。

Answer 1

我已經解決了。 我啟動了調試器，並在EsIntegTestCase中找到了一條日志語句，但沒有輸出。 因此，我修改了日志記錄配置，然后出現了來自彈性搜索的實際錯誤。

問題是字段映射不一致：
