ES is not starting. systemctl start elasticsearch Job for elasticsearch.service failed because the control process exited with error code. See "systemctl status elasticsearch.service" and "journalctl -xeu elasticsearch.service" for details.

Hi @greatvikas123, Welcome! It looks like you are setting properties that do not exist, in this case `node.master` and `node.data`. [As covered in this answer](https://discuss.elastic.co/t/elasticsearch-8-1-0-cluster-issue/302300/4), you need to use the [`node.roles` option](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html): `node.roles: [data, master]` Hope that helps! ---

What doc are you using? What install method? Always start with the config files from the distro, not from blogs, examples or non Elastic sources.
