Pretty sure I exactly followed the instructions here: [Install Elasticsearch with RPM | Elasticsearch Guide [6.8] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/rpm.html)

However tailing journalctl says the following. Anybody got any suggestions. I've very much a Dev, not Ops kind of guy 🙂 :

can you check and share the logfile of Elasticsearch as well as the journalctl output via `sudo journalctl --unit elasticsearch`?

Thanks!

Thanks!
