could someone share the coordinator node config for elasticsearch 7.8.1 version?
I tried with
node.roles: [ ] but its not accepting (i believe this is for 7.9 version) and throwing below error:
Caused by: java.lang.IllegalArgumentException: unknown setting [node.roles] please check that any required plugins are installed, or check the breaking changes documentation for removed settings
then it was considered as ML node.
it was considererd as Master Node.
