I know that embedded Elasticsearch is not recommended. I'm just trying it for testing purposes.

I'm trying to start an embedded Elasticsearch node giving the configuration from the following elasticsearch.yml

```
# Name for the cluster
cluster.name: elasticsearch
# Name for the embedded node
node.name: EmbeddedESNode
# Path to log files:
path.logs: logs
discovery.zen.ping.unicast.hosts: []
# Disable dynamic scripting
script.inline: false
script.stored: false
script.file: false
transport.type: local
http.type: netty3

```

I'm using es 5.1.1 and my code to start embedded node is as follows.

```
    try {
        Settings elasticsearchSetting = Settings.builder()
                // Value for path.home is required for es but will not be used as long as other properties
                // path.logs, path.data and path.conf is set.
                .put(ES_PROPERTY_PATH_HOME, "nullpath")
                .put(ES_PROPERTY_PATH_CONF, confDir)
                .build();
        Node node = new Node(elasticsearchSetting).start();
        logger.info("Embedded Elasticsearch server successfully started ...");

    } catch (Exception e) {
        throw e;
    }

```

I get the following trace.

```
java.lang.IllegalStateException: Unsupported http.type [netty3]
	at org.elasticsearch.common.network.NetworkModule.getHttpServerTransportSupplier(NetworkModule.java:194) ~[elasticsearch-5.1.1.jar:5.1.1]

	at org.elasticsearch.node.Node.<init>(Node.java:225) ~[elasticsearch-5.1.1.jar:5.1.1]
	... 18 more

```

I've tried with `http.type: netty4` as well but no luck so far. It works when `http.enabled:false` is set but I want to use http rest api for testing.

P.S:  
I've been using [this](https://github.com/elastic/elasticsearch-hadoop/blob/fefcf8b191d287aca93a04144c67b803c6c81db5/mr/src/itest/java/org/elasticsearch/hadoop/EsEmbeddedServer.java) elasticsearch hadoop class for reference in implementing embedded es and unfortunately I couldn't find any docs on `http.type`.

**Can't I start an embedded node with http now in ES 5.x ?**  
**What am i doing wrong here ?**

Any help is highly appreciated.

It's entirely not supported, so you are unlikely to get any assistance on this sorry to say ☹

Can we not use it even for test cases ?

@dadoonet Thank you very much for the positive reply. I'll take a look. 🙂

The solution was already [there](https://github.com/elastic/elasticsearch-hadoop/blob/fefcf8b191d287aca93a04144c67b803c6c81db5/mr/src/itest/java/org/elasticsearch/hadoop/EsEmbeddedServer.java) 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 plugins = Arrays.asList(Netty3Plugin.class);
Node node = new PluginConfigurableNode(elasticsearchSetting, plugins).start();

```
