Hi,
I recently upgraded to Elasticsearch 5.1 and found out that its compulsory to set Content type in my Integration tests. Right now i Get below error
> java.io.IOException: Request POST [http://localhost:9251/testindex](http://localhost:9251/testindex) HTTP/1.1 yielded text/plain; charset=UTF-8, should be json: HTTP/1.1 400 Bad Request
> at io.searchbox.client.http.JestHttpClient.deserializeResponse(JestHttpClient.java:179)
Anyone knows how to set a content-type for the response?
My current code looks like this,
> final Settings settings = Settings.builder()
> .put("http.port", port)
> .put("http.enabled", true)
> .put("path.home", "/tmp")
> .put("http.type", "netty4")
> .put("transport.type", "local")
> .put("cluster.name", UUID.randomUUID().toString())
> .build();
> Node node = new PluginConfigurableNode (settings, Arrays.asList(Netty4Plugin.class));
> node.start();
> return node.client();
> }
> private static class PluginConfigurableNode extends Node {
> public PluginConfigurableNode (Settings preparedSettings, Collection\\> classpathPlugins) {
> super(InternalSettingsPreparer.prepareEnvironment(preparedSettings, null), classpathPlugins);
> }
> }
