I am installing ranger using ambari blueprint using oracle database. Per https://cwiki.apache.org/confluence/display/AMBARI/Blueprint+support+for+Ranger, I need to provide root user password for ambari to create databases for KMS and ranger.
As you know, providing the root password is not a good practice due to security concerns. Can I manually create the databases and let ambari use these pre-existing databases so that I don't need to provide the root password? I don't see any document for this. Thanks for any hints.
