尝试启动嵌入式Elasticsearch节点时不受支持的http.type [netty3]

如@Bastian所述，问题是传输模块不在类路径中。该解决方案已经存在于es-
hadoop嵌入式es实现中。

private static class PluginConfigurableNode extends Node {        public PluginConfigurableNode(Settings settings, Collection<Class<? extends Plugin>> classpathPlugins) { super(InternalSettingsPreparer.prepareEnvironment(settings, null), classpathPlugins);        }}

我们可以给netty3作为插件，如下所示。然后一切正常。

Collection<Class<? extends Plugin>> plugins = Arrays.asList(Netty3Plugin.class);Node node = new PluginConfigurableNode(elasticsearchSetting, plugins).start();
