Hello Everyone,
I have an issue with my elastic search server, Even though xpack security is not enabled, elasticsearch JVM is trying load them and throwing error and not allowing to start this server.
This below value in yml files is already false, Am really not sure why this is behaving like this
Need help from this community
xpack.security.enabled: false
Below are my elasticsearch.yml files from two nodes and ERROR details.
