How to use DeleteByQuery plugin with embedded ES 2.3.3

I have run ES 2.3.3 in an embedded fashion but I'm unable to invoke the DeleteByQuery action due to the described exception. I added the DeleteByQuery plugin to my classpath and also set the plugin.types settings for my not but it is still not working.

My Maven dependencies: <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>2.3.3</version> </dependency> <dependency> <groupId>org.elasticsearch.plugin</groupId> <artifactId>delete-by-query</artifactId> <version>2.3.3</version> </dependency>

My ES Setup:

Settings elasticsearchSettings = Settings.settingsBuilder()
.put("threadpool.index.queue_size", -1)
.put("path.home", options.getDirectory())
.put("plugin.types", DeleteByQueryPlugin.class.getName())
.build();

NodeBuilder builder = NodeBuilder.nodeBuilder();
node = builder.local(true).settings(elasticsearchSettings).node();

Invocation of the action which is used to truncate the index.

DeleteByQueryRequestBuilder builder = new DeleteByQueryRequestBuilder(node.client(), DeleteByQueryAction.INSTANCE);
            builder.setIndices(indexName).setQuery(QueryBuilders.matchAllQuery()).execute().addListener(new ActionListener<DeleteByQueryResponse>() {
                public void onResponse(DeleteByQueryResponse response) {
                    if (log.isDebugEnabled()) {
                        log.debug("Deleted index {" + indexName + "}. Duration " + (System.currentTimeMillis() - start) + "[ms]");
                    }
                    sub.onCompleted();
                };

                @Override
                public void onFailure(Throwable e) {
                    log.error("Deleting index {" + indexName + "} failed. Duration " + (System.currentTimeMillis() - start) + "[ms]", e);
                    sub.onError(e);
                }
            });

Exception that I'm seeing:

Caused by: java.lang.IllegalStateException: failed to find action [org.elasticsearch.action.deletebyquery.DeleteByQueryAction@7c1ed3a2] to execute
    at org.elasticsearch.client.node.NodeClient.doExecute(NodeClient.java:56) ~[elasticsearch-2.3.3.jar:2.3.3]
    at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:359) ~[elasticsearch-2.3.3.jar:2.3.3]

I noticed that the Node builder invokes the node constructor with an empty plugin list. I extended the Node class in order to invoke this (protected) constructor.

public class ESNode extends Node {

    protected ESNode(Settings settings, Collection<Class<? extends Plugin>> plugins) {
        super(InternalSettingsPreparer.prepareEnvironment(settings, null), Version.CURRENT, plugins);
    }
}

Using the ESNode all the needed plugin was loaded.

    Set<Class<? extends Plugin>> classpathPlugins = new HashSet<>();
    classpathPlugins.add(DeleteByQueryPlugin.class);
    node = new ESNode(settings, classpathPlugins).start();

This may not be ideal but so far it is working just fine.
