Meaning of the "{USER}" and "{OWNER}" users in Ranger?

[#1]

When adding users to a policy, the values "{USER}" and "{OWNER}" show up, though they're not found on Ranger's user/groups list. Are they special values?

The same goes for other users on the list (e.g. one named "keyadmin"). I've verified that they're not being synced from the host unix system. Where are these other users being pulled from?

@Edgar Orendain Please refer the following wiki page

https://cwiki.apache.org/confluence/display/RANGER/Support+for+%24username+variable

"keyadmin" is a ranger internal user who has the ability to manage KMS related operations. Internal users are not synced from any external source, these are ranger specific users (and are available in Ranger db)
