Hi.
Starting to upgrade my System from 2.3.4 to 5.2.2 but now it won't start..
I get these error messages when I try to start it from the command 'sudo systemctl start elasticsearch':
It worked perfectly when I was on 2.3.4.
Procedure I took was
-
Stop ES
-
Removed all my plugins (license, marvel-agent, kopf and head)
-
Unloaded it and stopped the service.
I ran the update by d/loading the RPM and then running it. "wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.2.2.rpm"systemctl status elasticsearch -l
● elasticsearch.service - Elasticsearch

Any help will be greatly appreciated!
Thanks.
