How can the Ambari Ranger Admin internal user (amb_ranger_admin) be force recreated in Ranger?

enor — Tue, 19 Jan 2016 23:40:51 GMT

When installing an existing Ranger 0.4 into Ambari 2.2 to facilitate management in Ambari, the amb_ranger_admin user was not created in Ranger.

What is the simplest way to force this account to be generated?

This may help to clarify the question. I don't remember creating this user manually

To clarify, the account and password are correctly defined in Ambari, but they do not exist in Ranger Admin.

@Erik Nor

Have you enabled any plugin? Try enabling the plugin to see if it creates the user or not

Yes, the HDFS plugin is enabled. The user still doesn't exist.

Thanks to support we determined the problem to be either an incorrect/unset password for the Ranger admin user or HDFS needing to be restarted after enabling the plugin. One or both of these two things solved the problem.
