Elasticsearch throwing error

Elastic Stack Elasticsearch

I am using Elasticsearch 5.1.1 in my VM RedHat 6.8 Santiago. While trying to run elastic search, it is giving me below exception in the logs:

[2017-11-27T10:51:47,743][ERROR][o.e.b.Bootstrap ] Exception

I have run this as a root previouly without any issues, this time i am not sure why am I getting the above. I am using rpm for installation for the ELK stack. Kindly help.

You can not run Elasticsearch as root starting in 5.0.0. You could in 2.x with a special flag, but that flag is removed. In short: stop trying to run as root.
