I am using 6.3 version of ELK. Using the following configuration in elasticsearch.yml :

1. What is the username for elasticsearch ?
2. Can i set in yml like bootstrap.username=myname ?
3. I need to enable the email option with trial license to show a demo is it possible because if i add the configuration as mentioned below i see the configuration is not recognized message.

So i see that x-pack is already there with this version and trying to start with trial license, getting following exception :
