Elasticsearch 5.2.2 X-Pack: Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]

Elastic Stack Elasticsearch
1

Hi,

I have installed X-Pack 5.2.2 on Elasticsearch 5.2.2. I connect from java code to Elastic Search cluster, with none SSL connection. JDK is 1.8.102, I have all X-Pack jars at client classpath.
I have used following java client code:

https://www.elastic.co/guide/en/x-pack/current/java-clients.html

I am getting following when I try to establish Transport connection:

Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]
ElasticsearchException[Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]]; nested: InvocationTargetException; nested: ElasticsearchException[failed to initialize a TrustManagerFactory]; nested: NoSuchFileException[NOT_SET];

Any Input will be helpful.

Thanks,

It looks like you have an incomplete configuration of some X-Pack settings.

Can you provide:

  • The settings that you are passing to the PreBuiltXPackTransportClient constructor
  • The full stack trace of the exception, including the trace of the cause exceptions.

Thanks.

Thanks, Following are my settings:

Builder builder = Settings.builder();
builder.put("cluster.name","V2Dev2").put("client.transport.ping_timeout",60s);
builder.put("xpack.security.user", "abc:Pswd1234");
Settings settings = builder.build();
tclient = new PreBuiltXPackTransportClient(settings);

Do I need to Load XPackPlugin from Java code

Thanks,
Amit

I got the solution it seems X-Pack CertUtils.java
was trying to load, javax.net.ssl.keyStore=NOT_SET , so If I set this it worked!

Thank You!
