Hi,
I have installed elasticsearch-oss-6.6.1-1.noarch on my node. Document of elasticsearch releases says that X-Pack ships by default after ES -6.2. But in my elasticsearch.yml file I didn't find any X-Pack related settings. I tried it to give those settings manually by adding xpack.security.enabled: false as I want to use trial version for now but it also gave me an error . Please find the error in below log.
