Unsupported http.type [netty3] when trying to start embedded elasticsearch node
As mentioned by @Bastian the issue was that transport module not being in the classpath. The solution was already there in es-hadoop embedded es implementation.
private static class PluginConfigurableNode extends Node { public PluginConfigurableNode(Settings settings, Collection<Class<? extends Plugin>> classpathPlugins) { super(InternalSettingsPreparer.prepareEnvironment(settings, null), classpathPlugins); }}We can give netty3 as a plugin as follows. Then everything works well.
Collection<Class<? extends Plugin>> plugins = Arrays.asList(Netty3Plugin.class);Node node = new PluginConfigurableNode(elasticsearchSetting, plugins).start();
You need to add the module transport-netty4 to your classpath:
<dependency> <groupId>org.elasticsearch.plugin</groupId> <artifactId>transport-netty4-client</artifactId> <version>5.1.1</version> <scope>test</scope> </dependency>See also my answer here
