Hi Team,

I installed/configured Elastic, logstash, kabana on individual nodes.

I am seeing the below issue while logstash server startup, i followed this doc for logstash installations [Installing Logstash (Optional) | Beats Platform Reference [5.4] | Elastic](https://www.elastic.co/guide/en/beats/libbeat/5.4/logstash-installation.html)

Please format the log snippet as preformatted text (use the `</>` toolbar button) so that things don't get mangled. Specifically, what comes after "An unexpected error occurred! {:error=\>#"? And what does your configuration look like?
