Satyajit, thanks for looking into Ranger. I will try to take the first shot in answering your questions and let others chime in with more details…

Ranger UserSync is a separate process. You could have 2 instances of user sync running and pull user/groups from different sources. You might have to use different hosts, unless you want to customize conf and log folders. Please note, Ranger user database is just a reflection of what you have configured in Hadoop. If you are going to have both LDAP and Unix, then you have to make sure Hadoop also understands it. > Can I have regex in the for database / table names while creating a Hive > policy? Standard wild cards are supported. If you are looking more advances regex, then we can look into it or you can help us extend the current capabilities. >3. Does Ranger function properly with HDFS policy for folder name having "." >(dot) and "_" (underscore)? So far, I have not seen any complaints. Best way would be to try it out and see if you face any issues.

I am using Ranger 0.5.0.2.3 that comes along with HDP 2.3.2.0. I have a few questions as follows. 1. Is it possible to sync user simultaneously from LDAP and UNIX systems? In the Ranger's settings page, it is a radio button and only one can be enabled at a time. 2. Can I have regex in the for database / table names while creating a Hive policy? 3. Does Ranger function properly with HDFS policy for folder name having "." (dot) and "_" (underscore)? Thanks in advance for your time. Satyajit Banerjee
