Elasticsearch 6.2 start a localhost http node in unit test

These are no longer supported by elastic, but they work for Junit test purposes

I have the following

For 5.6.7

Settings.Builder nodeSettings = Settings.builder()            .put("cluster.name", "my-integration-test")            .put("http.enabled", "true")            .put("path.data", dataDirectory)            .put("path.home", "/")            .put("transport.type", "netty4")            .put("network.host", "_local_")            .put("transport.tcp.port", "19200-19400")            .put("http.port", "19200-19400")            .put("discovery.type", "single-node");    LOG.info("Starting up embedded Elasticsearch");    node = new LocalNode(nodeSettings.build(), Arrays.asList(Netty4Plugin.class,            ReindexPlugin.class));    node.start();

For elastic 6.8.3

        Settings.Builder nodeSettings = Settings.builder()            .put("cluster.name", "integration-test")            .put("node.name", "node-test")            .put("path.data", dataDirectory)            .put("path.home", "/")            .put("transport.type", "netty4")            .put("network.host", "127.0.0.1")            .put("http.port", "19200");    LOG.info("Starting up embedded Elasticsearch");    node = new LocalNode(nodeSettings.build(), Arrays.asList(Netty4Plugin.class,            ReindexPlugin.class,            CommonAnalysisPlugin.class));        node.start();

where

private static class LocalNode extends Node {    LocalNode(Settings settings, Collection<Class<? extends Plugin>> classpathPlugins) {        super(new Environment(settings, null), classpathPlugins, true);    }    @Override    protected void registerDerivedNodeNameWithLogger(final String s) {}}

For 6.8.x you will need

    <dependency>        <groupId>org.codelibs.elasticsearch.module</groupId>        <artifactId>analysis-common</artifactId>        <version>6.8.2</version>    </dependency>
