I'm running es-5.6.3 on rhel.
It works well with single and multi node configuration and basic attributes in elasticsearch.yml (cluster.name, node.name, node.master, node.data, network.host, etc.).
But when I added the node.host: xyz and node.group: group1 attributes to the config file and restarded the es, then the es not started and failed to pass the bootstrap process, giving the error:
ERROR o.e.b.Bootstrsp Exception
Suppressed: java.lang.IllegalArgumEcception: unknown settings node.host...., node.group, please check if any required plugin are installed or check the braking changes documentation for removed settings
I did not install any plugins in the node's plugin folder yet.
Which one need to be installed and where can I get them ?
I read the es 5 plugin docs section (there are multiple plugins) but still unclear which plugins need to be added in my particular case to fix the issue ?
Thanks in advance.
