Instantiate TransportClient in ES 7.8 help

I would like to replace the way I instantiate TransportClient in 7.8 since our application is heavily dependent on TransportClient at the moment. TransportClient will be migrated to RestHighLevelClient.

Settings settings = Settings.builder().loadFromPath(Paths.get("config/elasticsearch.yml").toAbsolutePath()).build();
TransportClient client = new PreBuiltTransportClient(settings)
                    .addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

This is no longer valid in 7.8 since the run time error occurs:

java.lang.NoSuchMethodError: org.apache.logging.log4j.Logger.debug(Ljava/lang/String;Ljava/lang/Object;)V

	at org.elasticsearch.threadpool.ThreadPool.<init>(ThreadPool.java:212)
	at org.elasticsearch.client.transport.TransportClient.buildTemplate(TransportClient.java:153)
	at org.elasticsearch.client.transport.TransportClient.<init>(TransportClient.java:298)
	at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:130)
	at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:116)
	at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:106)

It looks good to me.

What happens if you write instead:

Settings settings = Settings.EMPTY;
TransportClient client = new PreBuiltTransportClient(settings)
    .addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

Just to make sure where the problem is coming from...

But yeah, you should really move to the Rest Client. :slight_smile:

It produces exactly the same error. Any ideas would be welcomed.
