java - Elasticsearch 2.2.0 ESIntegTestCase : ensureYellow() results in “timed out waiting for yellow”

Question

我正在重写我们的集成测试以与 Elasticsearch 2.2.0 配合使用。 我有一个扩展 org.elasticsearch.test.ESIntegTestCase 的抽象测试用例类:

@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();
    }
    ...
}

我的测试用例类扩展了这个抽象类。它有 6 个测试，其中 3-4 个测试不断失败，并在上面的调用 ensureYellow() 期间显示“等待黄色超时”消息。

如果我注释掉 ensureYellow() 调用，那么在执行索引请求时我会从 Elasticsearch 收到“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]}]"
            }
        }
    }]
}

测试用例范围是ESIntegTestCase.Scope.SUITE，这意味着将为每个SUITE而不是测试创建一个集群，然后我在每个测试之前创建索引并添加映射。我假设每次测试后索引都会被删除，如 page状态:

By default the tests are run with unique cluster per test suite. Of course all indices and templates are deleted between each test.

有人知道我在这里做错了什么吗？

附注我正在使用 SBT 来运行我的测试。

我已经解决了这个问题。我启动了一个调试器，并在 EsIntegTestCase 中找到了一条日志语句，但我没有输出。所以我修改了我的日志配置，然后来自elasticsearch的实际错误开始出现。

问题是字段映射不一致:
