ElasticSearch：在本地模拟 ES 集群上安装 elasticsearch-mapper-attachments

Question

我在创建 ElasticSearch 的地方使用模拟实例 "locally" 这样我就不会在单元测试过程中或离线时依赖运行 ES 集群。例如：

Settings defaultSettings = ImmutableSettings
        .settingsBuilder()
        .put(ElasticSearchReservedWords.CLUSTER_NAME.getText(), "test-cluster-" + NetworkUtils.getLocalAddress().getHostName())
        .put(ElasticSearchReservedWords.PATH_DATA.getText(), new File("C:/Temp/mock_elasticsearch_cluster/data").getAbsolutePath())
        .put(ElasticSearchReservedWords.PATH_WORK.getText(), new File("C:/Temp/mock_elasticsearch_cluster/work").getAbsolutePath())
        .put(ElasticSearchReservedWords.PATH_LOG.getText(), new File("C:/Temp/mock_elasticsearch_cluster/log").getAbsolutePath())
        .put(ElasticSearchReservedWords.PATH_CONF.getText(), new File("config").getAbsolutePath())
        .put("index.store.type", "memory")
        .build();

String settingsSource = getClass().getName().replace('.', '/') + ".yml";
Settings finalSettings = settingsBuilder()
            .loadFromClasspath(settingsSource)
            .put(defaultSettings)
            .put(settings)
            .put("name", id)
            .build();
Node node = nodeBuilder()
               .settings(finalSettings)
               .build();

现在，它工作得很好，我可以索引和搜索...但是，我不知道如何安装插件。我介绍了附件类型，需要安装 elasticsearch-mapper-attachments 插件才能正常工作。

有什么想法吗？

按照 Andrei 的建议，我添加了

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch-mapper-attachments</artifactId>
    <version>2.4.3</version>
</dependency>

到我的 pom 文件（目前使用 ElasticSearch 1.4.1...）

当我添加

.put("plugin.types", org.elasticsearch.plugin.mapper.attachments.MapperAttachmentsPlugin.class.getNam‌e())

它给了我错误

1) A binding to org.elasticsearch.index.mapper.attachment.RegisterAttachmentType was already configured at org.elasticsearch.plugin.mapper.attachments.AttachmentsIndexModule.configure(AttachmentsIndexModule.java:32).

所以我删除了它...再次尝试运行我的 junit 对抗模拟 ES，它工作得很好！

我会尝试这样做：将 http://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-mapper-attachments/2.5.0 中的 jar 添加到您的类路径中。然后在 defaultSettings 中添加 .put("plugin.types", org.elasticsearch.plugin.mapper.attachments.MapperAttachmentsPlugin.class.getNam‌e()).
