I have a development cluster made up of 3 nodes. I installed Elasticsearch 5.1.1 on all 3, and Kibana 5.1.1 on just the first one. Installing X-Pack for ES and Kibana on node 1 worked fine and the services started back up again. I managed to hit the login screen and successfully authenticated with the default credentials.
However, the ES service fails to start on the other 2 nodes. I'm seeing:
org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]]; nested: InvocationTargetException; nested: ElasticsearchException[failed to initialize a TrustManagerFactory]; nested: KeyStoreException[problem accessing trust storejava.io.IOException: Invalid keystore format];
...
Caused by: org.elasticsearch.ElasticsearchException: failed to initialize a TrustManagerFactory
...
Caused by: java.security.KeyStoreException: problem accessing trust storejava.io.IOException: Invalid keystore format
The only mention of any SSL in my configurations thus far is in kibana.yml where I set server.ssl.cert and server.ssl.key for outgoing nginx requests. Not sure where these errors are originating from since this is a fresh install.
Any help is appreciated. Thanks!
