Unable to start Enterprise search. Throws org.jruby.ext.openssl.OpenSSL error?

Elastic Search
1

I correctly configured everything according to the documentation. But I'm really struck at this error:

    Unexpected exception while running Enterprise Search:
    Error: cannot load (ext) (org.jruby.ext.openssl.OpenSSL) at org/jruby/ext/jruby/JRubyUtilLibrary.java:201:in `load_ext'

I tried everything I can, but was unable to overcome this particular error:

  • Installed xpack security to elasticsearch
  • Correctly configured yml config files according to the documentation.
  • Ensured both elasticsearch and enterprise search are 7.9.2
  • Tested with both java 8 & java 11
  • configured elastic password, security encryption keys for enterprise search.
  • Elasticsearch is working perfectly, but Enterprise Search is failing to start.

It seems the error is related to the java version, as many other users who pointed to jruby error have resolved by switching the version of their java. But its not working in my case.

(Answering my own question.)

Well, I resolved the issue by upgrading the system to the latest Ubuntu (20.04) and using the default java shipped with the OS.
